Check if the following files exist:

> C:\Windows\inf\usbstor.pnf
> C:\Windows\system32\usbstor.sys

If yes, see my post in another thread about USB Mass Storage Driver Problems

Unless I'm missing a post somewhere, a WD 10EZEX is a SATA 6GB/s internal spinner hard disk drive and not a USB drive. Might I ask what drivers for USB flash drives have to do with a SATA internal hard drive? Thanks.

That's an excellent question. And I'm glad you asked.

On the one hand, I must have had USB on the brain from the start as I had just finished working on a USB thread.

On the other hand, when I asked the OP to check if those 3 USB storage driver files exist. The answer should have been "Yes, all the files are there". But the answer came back "No". So, either the answer was incorrect or there's more then one problem here.

Also evidenced by a flash drive didn't install. The driveclean tool uninstalls driver references from the registry. It only deletes registry keys. It doesn't delete files.

Perhaps the OP could clarify? In any case, attempting a System Restore is still a good thing to try.

Yes, I can clarify that for you ComputerGeek: in Post #2 I said that the three usbstor files were NOT on the machine that I was having problems with but they WERE on another (almost identical) machine in those folders. Like I said in my last post, I didn't copy them across because I wasn't told to.

I've followed the advice so far to the word, anyway let's move on and I can give you an update.

I copied those three files from the 17/02/13 folder like you said, re-booted and tried the memory stick. Wouldn't install, got no messages.

So I reconnected the old WDC drive, intending to do a restore. I've 2 screen prints, it's installed but I can't seem to access it to do the restore.

Just before Post #3, I had no problems accessing that HDD and it's never given me problems before (other than not having enough storage).

Appreciate any help towards getting the original and new issues resolved - thanks.

So on one machine, we have no USB drivers, and no drivers for a new hard disk; the old hard disk is recognized when installed and booted up.

I agree with ComputerGeek (and thanks for answering my question)...a System Restore would be a good idea, especially since it seems that the Registry's been altered. I might also suspect that SFC /SCANNOW could be run as well to replace missing Windows files... but I don't think that will fix the Registry.

I really hesitate to suggest a Windows Repair Install...

OldLaker... could you install the NEW WD 10EZEX in the other machine, just to confirm that the new drive is recognized by that computer and isn't DOA?

Ok, thanks.

System restored. USBs working and can access the old WD2500AAKX once more.

SFC / SCANNOW run. No integrity violations.

I'd already tested WD10EZEX by installing it on the other machine before posting on the forum (mentioned in #1). It's not DOA. However, if there's something we can learn from doing that again, I'm happy to try it out, let me know.

Looks like the issue is specific to desktop "A".

/ * EDIT * /

I just re-read the WDC specs. I did the upgrade to the WD10EZEX because it was in the same Caviar Blue family as the old 2500AAKX (expecting no surprises). The only differences are: cache (64Mb vs 16 Mb), data transfer rate (host to/from drive 150Mb/s vs 126Mb/s) and the EZ10EZEX needs more power. The only hardware differences between machines "A" and "B" are the backup HDDs, the PSUs and graphics cards.

When WD10EZEX is installed on "B" the driver is showing as 6.1.760.16385 in the Device Properties for the HDD. I have the same driver (name and date) on "A" when WD2500AAKX is installed.

Whooopie! We got your USB issue resolved! :)

OK. That's good and what i'd expect to see.

Question is: What do you see in Device Manager when the WD10EZEX is installed? I see an Other device in your earlier screen shot (that's disabled). You still have an Other device when WD10EZEX is installed?

Install the drive again

Click the Start Orb. Type msinfo32 in the search box, hit Enter
When the window opens, click the + sign next to Components to expand it
Click Problem Devices. Anything appear?
If yes, click on it, Ctrl-A to select all, Ctrl-C to copy it, Ctrl-V to paste into next post
On the other hand, if no devices are listed, tell me so

Ouch. Missed that. My bad.

Ok, well thanks I guess, I do appreciate all the time you've taken on this and best endeavours etc.

I've stopped at the point where the restore was done, so I won't mark this as solved. I can say why in full if you want it as a point of record.

The machine is working just fine again and I've decided to juggle around some hardware and will run the new drive on the other machine (where it works) and just be more careful about managing space on this machine where I'd intended it to be used. I'll take care of that myself.

I've provided a screenshot, more so you can reflect on the mystery (if you like) of all this. Those files didn't exist before the hardware upgrade attempt and the machine (with this hardware) runs just fine. The two HDDs (old and new) have been in and out quite frequently, I can assure you that when installing WD2500 (it searched and found the drivers) there is evidently no need for those 3 files. It's odd.
