I think it's a problem on my PC but I'm not certain. However, it used to work perfectly fine on my PC until just now.
Things I've tried so far:
-Unplug and replug: won't work.
-Tried other slots. Won't work.
-Restart my machine. Won't work.
-Tried other devices on the slots to rule out that it's a bad port. Other devices work fine so far though haven't tried other HDDs yet. Pen drives do work perfectly fine.
-Uninstall the driver, restart, plug it in and let plug-and-play reconfigure it. Still the same problem.
-Try it on other devices to rule out the HDD itself as damaged. Works perfectly fine on them. I'm making do with using pen drives and laptops as middlemen for my PC after this finding.
-Checked it out at Computer Management -> Disk Management. Says that it's not initialized. Did some searching on the 'net and it turns out that doing so has a good chance of ruining the HDD and since it works perfectly fine on the laptops, I decided not to proceed any further.
At this point I'm stumped. I'm suspecting it's a problem with the PC itself. Then there's the off chance of a brand new piece of malware that isn't detected by my security software with this as a possible symptom though my definitions are currently up to date. I'll see if I can borrow another HDD that used to be working fine on the PC to add to the data.
Edit: New finding. Managed to borrow an HDD that used to work on the machine. Won't read anymore. It's interesting that the problem is rather specific with external HDDs but other USB devices work fine.
Also, some specs:
-Windows 7 OS.
-P5KPL-AM EPU motherboard.
External HDDs tested:
neither are mine so I don't know the model numbers and neither do their owners when I asked.
