"I was playing around in Device Manager, unplugging and replugging the hard drive. Finally I found that although it wasn't listed under Disk Drives or Removable Storage
, it was listed under USB controllers. It had a little x on the icon. Upon right clicking it I found that it had somehow become disabled on my computer. I'm not sure how that happened. I know I didn't do it."

The first thing to do is to remove all the connections and re-insert them. Power and USB are the usual connections. You might try eSATA if you have the module. This is an old drive and even with only infrequent use, due to the lack of cooling on the drive, these will have an early failure. If you put your ear really close to the drive, do you hear a spin/stop/spin/stop sequence. Like the drive is spinning up and then stopping over an over? If so, that may indicate a crashed drive. Do you hear another noise or no noise at all?

Momentus is a SATA drive, so you can put it in any PC that has SATA bus to access the drive. If you can borrow a SATA to USB dock, you can put it in the dock and plug the dock to USB port on a computer to get your data out the drive. One example for the USB dock is EZ-dock and you can search on Internet for the picture.

Check the USB connection has enough power for the drive. Consider using a powered hub for the device. Change the USB cables for some nice new ones.

Wait for Win 8.2 or check for drivers at Forteinc

You need the software that you used to back it up unless you simply copied files directly. Most backup software creates it own backup format and extension that only its restore software or emergency boot disk can read.

If you recently ran a scandisk or disk diagnostic in this drive, it is possible that there was a bad sector on the drive and it involved the 12gb folder. In a case like this, I like to either make an exact copy of the drive using a utility like Norton's ghost or pull the drive out of the computer and connect it to another computer. Sometimes the main drive does not allow you to access certain folders because it contains critical system files. The other thing to make certain of is that you are signed in under the administrator account.
