I upgraded from Vista Home Premium SP2 (32Bit) to Windows 7 Home Premium (32Bit) and after the

upgrade my external usb hard drive can not be seen. The system notices it when it is plugged in

and/or powered on but does not show it under My Computer or any other drive display option.

I have seen other posts about this all without a solution- could I have missed the solution - if so

please forgive this posting and please point me in the right direction.

If there hasn't been a solution posted and you know how to solve this issue I am very interested.

The Windows 7 Hardware Compatibility indicates this drive is supported and the upgrade advisor did

not object to it.

Thanks

Open 'Administration Tools', select 'Computer Management', click on 'Disk Management' and see if

it can be seen here. If it does show here, chances are it doesn't have a drive letter assigned. If this is

the case, right click on the drive, select "Change drive Letter...', and assign a drive letter to it.

If it was not seen there, go to 'Action' on the menu bar, click on 'Rescan Disks' and it should come

up. If necessary assign a drive letter to as described above.

The drive does not show up and rescan does not cause it to do so either.

When I go into Device Manager there is a USB device with no name. When I click on update I get a

message that windows has determined that I have an up to date driver for USB Mass Storage

Device.

???

Thanks

Hi Lionel,

Please unplug unnecessary device, try other USB ports and see if the device can be recognized. If the

issue persists, please check if other USB devices can be detected.

Also, go to Start -> Computer -> Organize -> Folder and search options -> click View tab -> uncheck

"Hide empty drives in the Computer folder" -> OK.

What is the result? If the issue still exists, please move on:

Delete the Upperfilters and Lowerfilters value for USB device

=====================================

1. Click the "Start" button, type "regedit" (without quotation marks) in the Search" bar and then press

Enter.

2. Navigate to the following key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-

444553540000}

3. Right click the {36FC9E60-C465-11CF-8056-444553540000} entry, choose "Export", select Desktop in

the Save in box and type "backup" (without quotation marks) in File Name. Click Save.

Please Note: The backup file is on the Desktop and named backup.reg. We can simply restore the

registry by double-clicking the backup.reg file.

4. Highlight this key ({36FC9E60-C465-11CF-8056-444553540000} ), on the right pane, and then check if

Upperfilters and Lowerfilters value are present. If so, please right click on the values and select

"Delete" to remove them.

5. Restart the computer to check the issue.

Hope this helps.

Regards,

Linda

Having same problem with 16b usb pen drive. Worked previously on Vista system, still works on

other Vista systems, just not being recognized by Windows 7. I checked the registry key mentioned

here. I don't have either of the upperfilters or lowerfilters value keys....

Any suggestions?

I am having a similar problem that is baffling me with Windows 7. I have an external Maxtor USB

drive that Device Manager sees as a USB Drive but I am unable to assign it a drive letter and see it

in Windows Explorer. In the Disk Management Console it doesn't show up. I've already tried every

USB port and cleared the UpperFilter and LowerFilter entries in the registry....still nothing.

Any NEW ideas?

Thanks!

-Stephen

1. Plug in the external USB hard drive

2. Right mouse click on My Computer

3. Left click on Manage

4. Double click on Storage

5. Double click on Dick Management

6. Disk 0 is Hard Drive Partitions

Disk 1 will display the SIZE of the external device with no name

7. Right mouse click the BLUE BAR on Disk 1

8. Left click on Mark Partition as Active

9. Left click on Change Drive Letter and Paths

10. Right click the Add button - Right click OK

11. The external USB device should now have a drive letter

Hi - i tried your solution (using Windows7 with an Hitachi external drive) but my problem is - the

computer sees the new harddrive device , but will not open the drive for viewing OR At step 7 -

would not uninstall, just keeps running. This worked with my Maxtor drive (which had the problem

of not ejecting after i had tried to use the Hitachi). this Hitachi flaw requires me to force a shut

down "manually" and this is setting off alerts. Any ideas of what the problem could be?

thanks!!

hello

I still have problems with external drives mounting on Win 7 but with no drive letter attached don't

know the reason and the same drives on xp computers are no problem.

there has to be something about how windows 7 mounts drives and remembers drive letters

maybe the first service pack will address this issue.

anyway if windows sees the drive but cannot open it make sure you have a drive letter assigned to

it. Some of these external drives have a proprietary backup software etc which it requires to be run

before the drive can be mounted such as my maxtor one touch..

Hi, I also have a Hitachi that was not seen (same as most every one here) by windows 7 and had no

success with any of the methods described. I did however get it to work by using "delete volume" in

the disk manager then reactivating the volume. the only problem with this is it re formats the drive.

While doing step Number 7 I can not open the drive. There is only the option of "help", I tried using

the HD on a different system. Which did work, I know it is not a USB problem ( the darn things

worked on vista). I can see the drive in device manager but I can not open any files nor will it give

anything but the "safely remove hardware". Is there any way to open the drive or is this becoming a

lost cause with another windows product?

I had the same issue and it turns out my windows 7 install somehow didn't include 1 INF file that

allows usb mass storage devices to work: usbstor.inf

once i got a copy of that magically everything works properly. so to help everyone else out do the

following:

copy the text below the **

open notepad

paste the text you copied

save it as usbstor.inf

copy that to the windows\inf directory

uninstall any usb mass storage devices that are not recognized

unplug the usb mass storage devices you just uninstalled

plug them back in

here is the contents of the inf file

Make sure the following are on in your blackberry.

Go to options on your blackberry

Go to Memory and Make sure the following are on...

MEDIA CARD SUPPORT

MEDIA TRANSFER PROTOCOL

MASS STORAGE MODE.

"I could not find my blackberry either. It did the ding and all and still i could not find it. Then I found

out that I had my MEDIA TRANSFER PROTOCOL off. So I tured it on and BAM it showed up on my

computer.

MEDIA TRANSFER PROTOCOL

MASS STORAGE MODE.

I searched all day and night to find the solution as to why i could not find my blackberry. I did so

many differnt things that these ppl said and then I found a website that said those things needed

to be on. So i went into my phone just to check and sure enough I did not have MEDIA TRANSFER

PROTOCOL on. When i tured it on my blackberry showed up right away on my computer.

I'm using window 7 ultimate and the drive I was having trouble with was a 1TB Fantom Green drive.

This suggestion worked for me although initially I didn't think it was. See, when you are viewing

Disk Management in the computer management don't only look at the top part of the screen

where you see a list of your drives, also look at the list below which lists your disk as disk0, disk1

etc. My drive showed up there not in the top list. When I right clicked it - it showed me an option

to set it as 'online'. Once I did that it was all good. Hope this is helpful.

Update - I had also contacted Fantom support via email and I'm posting their reply.

------------ From Fantom Support ---------------------------------------------------

This is actually a pretty a common issue. When we format the drive here at the factory it is done

with an imaging machine. As such, each drive has an identical signature. Windows interprets this

as the same drive connected twice. To product the data is marks one of the apparent drives as

"Offline".

To resolve this issue you can simply reformat your drives. If that does not work (or you can't do

that) you can mark the drive as "Online" through the Disk Management console.

To access Disk Management open your Start Menu, right-click your My Computer icon (Computer

in Windows Vista and newer) and select "Manage." Disk Management appears here under the

Storage menu.

Disk Management is divided into two sections. The top section lists logical disks (i.e., C:, D:, etc.) and

the bottom section lists physical disks (i.e., Disk0, Disk1, etc.). Your second Fantom drive may not

be showing in the top area, but still show in the bottom area as an "Offline" volume. Simply right-

click the drive and select the "Online" option.

MicroNet / Fantom Drives

This worked for me on a new Dell Desktop in Windows 7 Professional for a Lacie 1TB External Hard

Drive.

1. Right mouse click on My Computer2. Left click on Manage3. Left click on Device Manager4. Expand the USB list5. Find the USB device for your USB Hard Drive (in my case it was the one that had no

description)6. Right mouse click - Uninstall7. Turn off the external USB hard drive8. Turn on the external USB hard drive and let it find and install the driver9. It should work

Uninstalling the USB Root Hub's and other USB hubs did not resolve the issue.

USB NOT RECOGNIZED-INSIGNIA PICTURE FRAME 9 IN

I have an ASUS with Win 7. The manual that come with the picture frame states that this is

supposed to be recognized as a USB DISK.

The USB is not recognized at all. I tried the method for the RIGHT-CLICK on MY

COMPUTER/MANAGE...etc-It is not shown as a disk; therefore, I can't rename it, etc. Then I tried the

copying tect for the 'missing' usbstor.inf but it is NOT missing on my Windows... I read all the other

posts.

Pls. advise. THx!

I have tried all the solutions on this page and no luck. Incidentally, the drive does not show up in

disk management to assign a drive letter too, but windows does recognize it. Windows 7 pro fresh

install.

I was having the same problems with my acomdata PureDrive. I tried a couple different things. First

I followed the procedure above that Lionel provided, but that didn't work for me. Next I went to

Disk Management. I couldn't see the drive in the top window pane, but in the bottom pane I could

see a drive that was blank (it appeared as a Dynamic Drive). After moving all the files from the

external drive to my desktop I right-clicked on the blank drive in the lower pane and chose "Make

basic drive", then I right-clicked on it again and chose "Format" and it finally appeared. I am

assuming it should be a NTFS drive.

Now it appears in My Computer and Disk Management, as well as Device Manager.

Had the same problem as the first post - "The system notices it when it is plugged in and/or

powered on but does not show it under My Computer or any other drive display option" - when I

bought a new computer with Win 7 as the OS. I wanted to copy stuff from the old 'puter hard dive

so I used an external drive patch cord. Nothing worked. Then I remembered having the same sort

of problem on a Red Hat system with a flashdrive. I used a shorter USB cable and there was the

drive! Everything worked OK and I was able to copy over my old files. Don't know why I had the

problem inasmuch as I have used that cord & adapter many times before but that was the problem.

Sounds simplistic but you might give it a try.

I have the same problem and none of the above solutions work. I have a Toshiba ALU 3.5" 1TB that

works fine on my old mac and another macbook but not on my Toshiba Satellite L670-117 that I

purchased yesterday. It sees it as a device but it isn't listed as a drive in My Computer so I can't

access any of the files on it.

I've uninstalled it from device manager and turned it back on and nothing changes. In Disc

Management "Mark Partition as Active" and "Change Drive Letter and Paths" are greyed out so I

can't click them.

The hard drive is a couple of years old and according to the box is only compatible with OS up to

Vista. Could this be the issue? I've installed the most up to date driver available for it.

Please help!!!

Thanks

Steve

This is what worked for me after trying many of the solutions offered above. I wish I could claim the

credit but this was originally posted by GANKS on one of the MS websites mentioned above. Hope

it works for you. If it does and you have asked the question on other forums then please post the

solution on those forums too and help to spread the knowledge.

Cheers

**************************

Symptoms:

USB shows in the device manager (right click on my computer and click manage, devices) either

"Unknown USB device" or "name of USB hard drive manufacturer" both of which have the yellow !

next to them saying they aren't installed correctly.

Resolution :

Right click on the device in the device manager that shows it isn't installed, click update driver

software, enter this location assuming your C drive is your main drive

"C:\Windows\winsxs" and ensure the box is checked to include subfolders and hit ok. It should

reinstall immediately and show up as a new drive in "My Computer"

You may have to uninstall the device first, replug it back in and then run through the above steps.

This is what worked for me.

After clicking "Manage discs" I had blue bars for old discs and black bar for new unseen disc. I right

clicked, did not get the menu described above but had the option to make a simple partition (or

less simple but in different words). Windows then suggested size, format and drive letter. I accepted

defaults, the bar turned blue and explorer recognised the disc.

I hope that helps the rest of you!

Wow! I had been struggling with all sorts of USB Mass Storage issues and was even considering re-

installing my computer, but Rob's solution of restoring usbstor.inf completely fixed it.

BTW: I checked my backups and that INF file was deleted by an installer that came with a mobile

phone.

Yay!

Same problem with my brand new Toshiba Satellite notebook PC with Windows 7 installed. External

drive is Hitachi, which worked fine for years on my old Lenovo laptop / Windows XP.

Yes, the new PC 'notices' the drive but does not recognise it or assign it a letter, nor can I open it.

Driver update didn't work. Also, there was an uncomfortable clicking sound coming from the

external drive when plugged in, as if the PC was trying to access it but unsuccessfully.

The solution was supremely simple and it worked for me on my systems. It may not work for

everyone though.

My new PC has 2 USB 2.0 ports and 1 USB 3.0 port. I have no idea what the difference is between

the two.

Since I need to plug in lots of gadgets, I got a 4-port USB hub. My mobile broadband modem uses

one of the PC's USB 2.0 ports. The USB hub goes into the other USB 2.0 port, and my mouse goes

into one of the hub ports. And I had plugged my external drive into the USB hub. Then I got the

problem. Nothing! Couldn't access or open the external drive.

Updated the driver for the external drive, did that from the old PC. Back to the new PC, still nothing,

same situation.

So I took out the 4-port USB hub from the new PC, and plugged the external drive directly into the

PC's USB port. And, lo and behold, I was in business again!! Everything worked beautifully, the way

they should. Without having to do any kind of reconfiguration, workarounds or system tweakings.

Even tried plugging the external drive directly into the PC's USB 3.0 port. Worked fine too!

Maybe Windows 7 doesn't recognise devices which are connected to the PC's USB ports with more

than one connection.

Haven't tried it yet but it may also be possible to include the external drive as a device added to a

network or homegroup. I can see and access the external drive from my new PC, if it is plugged

into my old PC. The old PC is part of my network (through LAN cable) which was created on the

new PC with Windows 7.

Hi Shooter

I had a similar problem with a new Kingston 16gig USB pen, it showed up in "Disk Management",

"Devices and Printers", and the USB icon came up in the "System Tray" (although it didn't display

the device just 3 dots), but not in the "Computer" console.

I tried every thing here but nothing worked.

here is an easy work around i figured out to the problem.

FIRST! insert it into a USB port and make sure it shows up in "Disk Management", "Devices and

Printers"

and the USB icon shows up in the system tray (even if it wont display the device name when you

click the USB icon, it may show 3 dots),

if it is showing up in all 3, click on it in "Disk Management" and see if it has a drive letter,

if it hasn't got a drive letter set it to "Z:\".

then right click it in "Disk Management" and select either "Open" or "Explore"

if it will open and you can see the files on it, then this may help as a quick fix for the time being.

1) with the USB pen in a USB port, open the "Devices and Printers" control panel, double left click its

icon to open it's properties,

click on "Hardware" tab, highlight it and open its "Properties", set its "Policies" to "Quick Removal",

this way you can insert and remove it with out causing any problems to it, close its properties.

2) open "Computer Management" console, click on "Disk Management" right click its entry, and

change its drive letter to "Z",

if you haven't done so already.

3) right it click again and select either "Open" or "explore"

4) if there are no files on it create a folder and call it "Files", right click and hold the folder then drag

and drop it onto the desktop, and select create shortcut, rename the shortcut to "USB PEN".

5) right click the shortcut and select "Properties" in the "Shortcut" tab, change both the "Target"

and "Start in" paths to "Z:\".

(changing the "Target" and "Start in" paths to "Z:\" will prevent windows asking if you want to delete

the short cut, if you click on it when the USB pen is not in the machine, instead nothing will

happen.)

6) open "Computer" now either copy and paste or move the shortcut to the "Favorites" folder in

the left pan of the "Computer" console panel.

7) with the USB pen in a USB port click the shortcut and see if it opens the USB pen.

if it opens the pen you can now delete the folder we created on it to make the shortcut.

hope this helps.

Don't know why I had the problem inasmuch as I have used that cord & adapter many times

I'm actually using ole Windows XP and am having a similar problem. I popped out a circa 1995

laptop hard drive (yes, there were laptops then) and put it into one of those external enclosures

that provide a USB connection. (I'd used it before with other laptop hard drives with no problems.)

After providing power to the hard drive enclosure (5V) I plugged the USB into my current laptop

USB. The laptop (Windows XP) detects the hard drive and it even shows up in the Device Driver

under Disk drives as "ST9190AG USB Device". If I right click and select Properties the Device Status

is "This device is working properly." However, I cannot access the hard drive, because it does not

appear in "My Computer" or "File Explorer". Usually when a device is detected it appears there

along with the C drive, etc. I have tried refreshing. It is a Seagate ST9190AG. I have the manual

but I can't figure this problem out.

Any thoughts?

In my case the solution was: 1.Plug in and turn on the external USB hard drive 2.Right mouse click

on My Computer 3.Left click on Manage 4.Left click on disk management 5.Right click on the

square area that contains (Disk#) on the lower left portion of device manager(you will notice in it a

small disk icon with red arrow pointing downwards and an "Offline" description beside it. 6.Choose

(Online) Thats it. I hope this was helpfull

It worked for me too :). Must be a bad installation of the driver. So don't be afraid to uninstall it, it

will just reinstall automaticaly because it's an USB device.

All,

I just want to share with the community how I solved the problem. I did read all the entries and

posts here, and from some other sites. I tried with many of them and nothing solved the original

problem: my Iomega USB 2.0 external drive was recognized but not really detected by Windows 7

64-bit. The way I solved it was: REFORMATTING THE EXTERNAL DRIVE with NTFS. I previously

backed up all the information on a XP computer, then reformatted the drive. After that, I could work

with the drive.

I know it's hard to spend hours and hours trying different options. That was my experience.

Another solution (it worked for me)

Open Windows Explorer and right click on the LaCie drive (which is my external drive) and go into Properties.

Go into Advanced Sharing on the Sharing tab and tick the Share this Folder box. Ok out.

I had the same problem!!!

I fought with Windows7 when I plugged in an external hard disk that I made up recycling an old

laptop hard disk.

Ubuntu recognised it immediately. Windows did not let me use the drive.

In Disk management I can see the drive, but it was not shown in "My computer". I could not

rename it immediately (grey option).

So.. what I did.. (MY SOLUTION):

Disk management -> right click on hard drive partition that I wanted to use -> delete (Be careful,

do a back up first, using another computer).

After delete.. format -> so you can assign a letter to the hard disk, and a name ecc.. -> IT'S OK (I

have then unplugged and plugged again ecc..) -> it works!!

I Hope this comes in help

___________

now I've read another post up here with basically the same solution proposed.. so.. format to ntfs :)

I don't know if my issue is similar to someone, here.

Some time, my pendrive or external HD is disconnected, when reconnect it, not show it under "my

computer". Not assign letter. Any partition software can see it, but cannot assign a letter. Device

manager show it, but cannot populate a volume. This issue persist until reboot the system. No

driver problem, is only a disk manager problem. Under Manage -----> Storage ---> Disk

Management not show the disk. I have a lot of diks (5 HDD) and 3 external drives.

I have Windows Vista x64 Ultimate.

Resolved :




10. It should work

Lionel B. Dyck

I have currently come across the issue that was resolved with this method. I have a Manhattan 2.5"

Hard Drive Enclosure for a hard drive that was taken out of my old laptop. A friend has a device

that can check the health of hard drives, and we were able to determine that the actual drive is still

good. When I upgraded to Windows 7, though, my hard drive is no longer recognized by windows.

It makes the sound showing that it notices when the enclosure is plugged in, but it does not show

the drive in computer or any other listing. I've tried this method in an attempt to fix this issue, but

was unsuccessful. Any idea how to fix this? Any help would be greatly appreciated.

I used Linda Yan's solution and it fixed my problem. My question now is, should I backup the

registry to restore that key modifier or just leave it out? The system seems to be running fine

without it and nothing is complaining. I only had the lowerlifters value, but I'm wondering why it

was there if it isn't needed and what if any, exposure I have without it.

thanks for the great tip!!

Hi all,

I got weird problems with the same symptom. Windows 7 Ultimate 64 bit recognize USB Hard Disk

but can't see the filesystem (NTFS) on it. Disk Manager connecting to Virtual Device... forever and

Explorer assign the Driver Letter but show up "WAIT" icon... forever until you kill it or reboot.

My HDD is Western Digital Green Caviar 2TB, partitioned with classic mode with 1 Primary Volume

formatted NTFS in Windows 7. Then I attached it to a Linux NAS via USB port to copy files from

NAS, using ntfs-3g drivers that allows read/write to NTFS partition. Everything runs perfectly until I

attached it back to my Windows 7 as above said.

This problems happens to me couples of time with some HDD of other sizes. The only solution is to

unload those files to NAS, reformatted and recopy, which takes 1 day.

My HD Player also can see the files on the disk, my Linux NAS can see and read/write as normal, my

Ubuntu Laptop can see and read/writes. Only Microsoft Windows 7 can't see it own child.

I am about to convert all my Extermal HDD to Linux Filesystems, but then I have to use VMWare on

Windows to read/write external hard disks.

I tried several HDD recovery software but all they are helpless since Windows can't connect to

Virtual Device Drivers that talk to NTFS partition.

Appreciate your advises

I had same problem fixed real easy could have kicked myself when i found solution

-in device manager -disk drives- policies- change usbs from quick remove to use the safe hardware

remover and then do the same for specific usb- strangly for me it was only my self powered usb

ext/int that gave any trouble.-- which should live on your taskbar in what I think is called the quick

launch down right anyway.

Thanks a lot. It did work perfectly for me. I was very reluctant to upgrade to win 7, but when i did, i

didn`t regret it at all. Then came this USB issue and said, oh my gosh...self fulfilling prophecy...funnily

enough,my laptop (win7 OS) recognizes all my USB drives, but my desk doesn`t. Now problem

solved.

"windows 7 not detecting usb device"

"usb device not recognized windows 7"

"usb device not recognized by windows 7"

Step 1:

C:\Windows\System32\DriverStore\FileRepository\usbstor.inf_x86_neutral_83027f5d5b2468d3

Copy the below files:

USBSTORE.INF

USTSTORE.PNF

USBSTORE.SYS

Paste the files in

C:/Windows/inf/

Step 2:

Then go to device manageer (START, serach program and files for Device Manager, then click it). It

will show a list

of devices, and half way down is an 'UNKNOWN DEVICE' with the yellow icon next to it. Right click

that and

'reinstall driver' or 'update driver software' - > Browse my computer for driver software -> Put the

path 'C:

\Windows\inf'..

This should install the USB devise

Step 3:

If you get an error while installing that, the next step is to go to

C:/Windows/System32/drivers/USBSTOR.SYS

and paste the file USBSTOR.SYS file only mentioned in Step 1 (if prompted to replace, pls allow)

Disabled due to Kidney D... 0 Points

Hi all,

Hope everyone had a wonderful Turkey Day and that y'all aren't all wiped out from standing in line

at your retailer of choice all night!

I have a similar but slightly different issue with W7. I'm using a Bytecc USB Adapter (See here if,

perchance, you're not familiar with this doo-dad) to see what is on a couple of old IDE hard drives

and to determine whether to use them in another project.

I'm roughly 99% sure what the answer will be since these are circa 1995 HDDs but I'll ask anyway....

:-P

I tried the solutions in this thread with no positive results. Rather, what I'm facing is in Disk

Management, where my only option is to initialize the disk which, of course, defeats the purpose of

my "experiment." My only options are "Initialize," "Offline," "Properties" & "Help." My desktop has

only one IDE port which is connected to one of my DVD R/W drives but that's where I'm thinking of

going next. But I am a little worried that it'll just be "same problem, different cable" and that I spent

the afternoon rearranging my desk to crack open my case.....

Thanks in advance for any and all advice!

Jack

I'm out of my mind, please leave a message

Hey Lionel,

I have a IOMEGA external drive and all the sudden it stop being recognized on my Win7 32Bit.

It doesn't show on Disk Management nor Device Manager when I go to

Star>Computer>Manage>Disk Management/Device Manager

I read what you wrote above but couldn't understand what you meant by

Start>Computer>"Organize"?>"Folder"?

Could you clear that up please?

Also when I go to Disk Management the only drives that show or that are even assigned to a drive

letter are my internal PC hard drive C and my CD/DVD Rom drive.

So how could I even change or assign a letter to a drive that doesn't even show..

My IOMEGA external hard drive does swith the light on and is working because I can feel it

vibrating a little and heats the normal way as if it were working like it used to.

Thanks:)

delete the upperfilter and lowerfilter..so what now?The only drives taht show up are my Hard Drive

and my CD/DVDRom drives.. it just stopped being ecgnized from one minute to another. I jut

swithed it of to 0 and then back to 1 because I was safely removing a pen drive and didn't want to

remove the wrong one so I did that and when I turned it on to 1 again nothing happened. The light

switched on and you can feel it working and launching xcept not on the PC..tried every other USB

port as well as my uncle's pc.. nothing..

I'm using Windows 7... always did and no problem, but about a month ago..this happened..I have all

my pictures and all my important documents on it!

Please help!

My Toshiba 320GB portable hard drive is not showing up. Have tried different option mentioned in

this forum.

So far, this is the current status:

It is being recognized just with sounds by the computer after plug it in, and the unit ispowered upIt is not showing under My Computer.In Device Manager, under Disk Drives it is shown as "Generic Multi-Card USB Drive"In Disk Management is not showing up at all

The data that is there is very important, and I will like to save it. Can you tell with the above

information if the data is there and is not lost. And also I havent tried the uninstall option of the

drive, because I am not sure if doing this I will definitely loose the data.

Any help will be deeply appreciated!!

Try to unplugg the disk, restart the computer and plug in again. U can uninstall the driver, this no

affect the data. After restart, and plug in, driver reinstalled it self.

Or try to use any disk partition software to see if data still there, or plug in another computer, or

download a linux boot cd and restart with them to see the data.

Ok if you are not bothered about whats on the external harddrive/usb stick here is what you do.

Note your hard drive will get formatted

Right click "computer"

1. Click manage2. Click click management on the left3. In the list you will see your disc drive, "disk 1" probaby4. Right click in the right hand cell of the "disk 1" table. You should get a creat volume option5. Select this create volume option and follow all the steps6. You will now find the hard drive has been formatted7. Now do the below, this time it will work




10. It should work

I recently had a similar problem with Windows 7 Home Premium SP1 64-bit. I had a Seagate 60GB

drive that I had removed from my Gen1 PS3. I installed the drive into a nexStar 3 external 2.5" hard

drive enclosure utilizing the USB 2.0 interface.

First, it took forever to get the enclosure to be recognized, at all. I had to take the USB 2.0 cable

from my 250GB from my 250GB Seagate FreeAgent Go drive and put the "power only" connector

into my rocketfish USB hub and the data/power connector into a front USB port. At this point,

Device Manager FINALLY found a "USB Storage USB Device" disk drive. Yet, there was no disk drive

identified in Computer.

I followed the advice given by Lionel B. Dyck above and only succeeded in un- and re-installing the

"USB Storage USB Device" driver.

The happy ending is I followed your advice and, after a few trials and errors, I was able to create a

dynamic(?) drive that was reformatted into NTFS and mounted as drive L: (vice the enigmatic Disk

7).

Many thanks!!!
