I have a desktop PC (Windows 8.1) and I use 3 external hard drives that connect via USB 3.0 ports. Recently, one of them would lock up after some time after a boot. Now it seems it locks up almost immediately. I might be able to view the root folder, but it would freeze up upon trying to go into subfolders and opening files.
I've tested all the drives on another PC, and they work fine. If I put in a temporary HDD and try a clean format of Windows, it works fine. If I reboot into safe mode with networking, it works. Swapping around the USB ports used doesn't resolve it.
I'm not sure what could be causing it. I took a look through startup items and there isn't anything that shouldn't be there. I've followed the steps on these pages:
Any ideas? If I could resolve this without a full reformat of my working drive, that'd be great.
