USB pen drive detected but doesnt show up in My Computer or Disk Management

From Google, there are many kinds of situations. Mostly are telling me to go disk management but my disk management is empty except for the CD-ROM. Only the Device Manager detects the pen drive. I can’t access it from the Run command either. Another thing is that the system tray also showed that I plugged in a pen drive and can be safely removed. The pen drive worked earlier with this laptop (An old Toshiba laptop with Win XP Pro - SP2) and still works in other computers.

I'm out of ideas here and hope for someone to solve this case.

Please....
Thank you...

 

Did you customize the configuration for the pendrive, such as setting it so that it's optimized for been taken out?

 

I had a similar issue with a USB photo keychain device. Here is what I had to do to solve it. Note that the INFCACHE.1 will be automatically rebuilt. But if you are at all worried you can just rename it in step 10, below. The note below was with an issue of the driver not being found, but it also cured my situation of not seeing the device once it was installed.

When trying to install a new device (like a USB mouse, printer, video card, etc.), Windows Vista might report that there is "no driver found for you device [sic]" and/or will not display the pre-installed Vista OEM drivers. Even by manually selecting the driver, you will still get the "no driver found..." error. This also tends to happen with HP printers (as we know their drivers are bulky and complex). You will get a red X at the end or it won't find the drivers - again.

This is caused by a corrupted INFCACHE.1 file. This file is hidden, has restricted access, and can be found in "c:\windows\inf". This file stores the location of drivers and their INF files.

Delete this file and it will force Windows to rebuild the INFCACHE.1 file the next time Windows searches for drivers.

To delete this file, you have to set the security permissions of it to allow Full Control for the User Group Administrators or full control for your account. Here's the complete how-to:

1. Open a Windows Explorer window (right click Start> Explore)
2. In the address bar, type c:\windows\inf and press Enter
3. Right click on the file INFCACHE.1
4. Select Properties
5. Click on the "Security" tab
6. Click "Edit" to edit permissions
7. Click "Add" to add User Groups
8. Type "Administrators" in the User Groups field and click ok
9. Set Administrators to "Full Control" and click ok
10. Move or delete the file "INFCACHE.1"
11. Reinstall a device to force Windows to rebuild the "INFCACHE.1" file

 

Is this ok for Windows XP becouse my machine is Win XP.

 

As far as I know yes, but I have NEVER tried it on an XP machine. Just make sure you copy the original infcache.1 file somewhere, that way you can always copy it back if necessary.
