PEN DRIVE DETECTED BUT DOESN'T SHOW UP IN MY COMPUTER

You may have faced a problem when you insert your pen drive and it gets detected very easily but it doesn’t show up as a drive icon in My Computer. The computer detects the pen drive but data on pen drive is not visible as the pen drive is not visible in My Computer (Explorer).


This problem occurs mainly when windows XP fails to allocate a drive letter to your portable drive(pen drive). It occurs mostly with new pen drives connected to your computer for the first time. If you face such problem then it may not be the pen drive’s fault, rather it may be windows trouble.






You can fix this issue by following some simple steps given below.

• Click Start, click Run, type compmgmt.msc, and then click OK.

• In the console tree, click Disk Management. The Disk Management window will appear.

• On this disk management window, you can see some drives including the portable drive. Right click on your portable drive and click change drive letter and paths.

• Now a assign a new drive letter which is not being used by any of your drives in My Computer.

• After assigning the new drive letter your portable drive will show up in my computer with other drives

While in some cases 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:

• Open a Windows Explorer window (right click Start> Explore)
• In the address bar, type c:\windows\inf and press Enter
• Right click on the file INFCACHE.1
• Select Properties

• Click on the "Security" tab
• Click "Edit" to edit permissions
• Click "Add" to add User Groups
• Type "Administrators" in the User Groups field and click ok
• Set Administrators to "Full Control" and click ok
• Move or delete the file "INFCACHE.1"
• Reinstall a device to force Windows to rebuild the "INFCACHE.1" file

I hope the above solution will help to fix this trouble.
