Next, I'm curious... do these two files currently exist? C:\Windows\inf\usbstor.inf and C:\Windows\inf\usbstor.pnf

These were the two crucial files that were missing on some other user's PC with the identical problem.

I made mention of this up in post #4 above, in which I provided a link to the web article on this identical problem for another user of failing to properly recognize the same WD drive exactly as OP in this current thread:

"The user still had problems, and discovered that USBSTOR.INF and USBSTOR.PNF were somehow missing, as described by this other article. "

nope i checked this yesterday they were there
imdoing the clean up now so hopefully it works

First, a recommendation: Turn off the Folder Option that hides file extensions. I find it only makes it more confusing and easier to misidentify files and their file type. CtlPnl->Folder Options->View. Scroll down and uncheck the box to hide file extensions for well known file types.

Next, I'm curious... do these two files currently exist? C:\Windows\inf\usbstor.inf and C:\Windows\inf\usbstor.pnf

Next, run the DriveCleanup Tool.

Next, we'll try to recover files from your Windows FileRepository.
> Look in C:\Windows\System32\DriverStore\FileRepository
> Find and open the most recent folder (there may be more then one) whose name starts usbstor_inf
> Copy files usbstor.inf and usbstor.pnf to the Windows\inf directory
> Copy usbstor.sys to Windows\system32\drivers directory
> Delete the INFCACHE.1 file as you did before
> Reboot your machine

Try connecting the drive again

/* EDIT */
Added instruction to run DriveCleanup Tool

ok didn't work

ugh.

fyi... When the INF is missing from Windows\inf it's a somewhat different case then yours. That case generates the "unknown hardware" messages because Windows needs the correct INF to identify the device. In your case, the INF is there, but the driver executable usbstor.sys doesn't have correct digital signature for Windows to be happy

One quick thought before i look further, don't know if mentioned yet but have you tried a System Restore?? maybe there's a System Restore point where the correct USB Mass Storage driver files are still there.

i did but my restore point is quite recent
well i wanna try the 2010 usbstor_inf it might work u never know

Yup. Good idea. is worth a shot. If still doesn't work

Shoot it didn't work i gave me the blue screen of death

btw... When I look at my own Win 7 x64 machine i have the same folder

C:\Windows\System32\DriverStore\FileRepository\usbstor.inf_amd64_neutral_0725c2806a159a9d. The MD5 checksums on the files follow. You can see if yours match

usbstor.inf 9A189C77A3B6B084F25C30054F64FD71

usbstor.sys D76510CFA0FC09023077F22C2F979D86
