Windows 7: USB flash drive can't be accessed

USB flash drive can't be accessed

Hello folks, I have a new Kingston USB 8GB and whenever I plugged it into my desktop PC it can't be accessed or opened. When I open "Devices and Printer" it can see my USB called "Data Traveler 2.0" but I can't open it. I tried uninstalling the drivers and plugging and unplugging it but still the same results. I tried opening the Disc Management and it can see the USB but when I try to format it or try to assign a drive letter error pops out. The USB drive works on my laptop except the desktop PC that I'm using. Also, I have the same issue with External hard drives being recognized but I'm unable to open/access it. Basically, the problem lies within my PC and I don't know what to do .

This is what happens when I try to change the drive letter/paths:

Any help would be greatly appreciated.

Hi Lacerate,

Try drivecleanup as in my post USB Thumb Drives not recognised (not drive letter) and check whether it resolves your problem.

I tried this. Leaving my mouse and keyboard only plugged in as I run the drivecleanup. It deleted many registries and when I plugged the USB it starts re installing for the drivers and the USB was recognized but can't be accessed. I think the issue is that it can't find the volume of the USB

Does it show up in Disk Management?

If it does post a screenshot.( Please use Windows snipping Tool and upload it using Manage attachments while posting.)

It's pretty much the same 2 images above that I posted.

OK. Please do the following.

1. Open Windows Explorer and navigate down the hierarchy to C:\Windows\System32\DriverStore\FileRepository and look for one or two folders with the name usbstor.inf_xxxxxxxx. Open the folder with the latest (newest) date.

2. Open another instance of Windows Explorer and navigate to C:\Windows\inf.

3. Place the windows side by side.

4. Go to the first window (1 above) and copy both the usbstor.inf and usbstor.PNF files to the second window’s folder (C:\Windows\inf).

Reboot your PC and then plugin your USB drives and check whether they show up now.

I am now retiring for the day and will be up again after another 10 hours.

If the above does not resolve your problem then the infcache.1 file has to be rebuilt. Hope someone else here may help you do it.

I tried those methods above and still doesn't work. Even deleting the INFCACHE.1. It just rebuilds itself.

1. Reinstall the latest chipset drivers for your motherboard. ( Check your motherboard manufacturer's website.)

2. Try a System Restore to the earliest point you can get on your system.

If these do not resolve your problem, repeat 1,2, and 3 as in Why aren't my USB Device Divers not working on my laptop?

If all these do not resolve the problem, then I would think a Repair install as indicated in the referred post is the answer.

Wait to see if other experts have any ideas on resolving the problem before going for a Repair install. I could have missed something.
