Windows 7 Professional doesn't mount my usb flash drive anymore

I have a Kingston flash drive which works fine in every computer that I insert it. But in my Windows 7 it doesn't mount anymore.

Why this is happening ? When I insert the flash drive it seems that the Windows 7 recognize it, but when I hover the icon don't show the flash drive to remove it, as usually does.

Any idea ?

Thanks.

Any idea ?

I had the same problem. My thumb drive always worked on my main computer running Windows 7 with no problems. All of a sudden for no reason whenever I plugged it in it would show up under computer but not showing the correct volume name and when I tried to access it I would get an error message. The thumb drive still worked perfectly in all other computers, including my laptop also running Windows 7, and two computers at work, 1 runng XP and the other running Vista.

This is what I tried as a long shot and it worked. I backed up my thumb drive on to my laptop and then I formated the thumb drive. After that it worked fine in my main computer again. if anyone is havibg the same problem try this, it worked for me.
