Hi, i am running windows vista on my HP desktop computer, and i am trying to back up all my files onto an external hard drive so i can deal with a hard drive problem. The bigger problem is that i think that my hard drive problem is preventing me from backing up my files. before i go my external hard drive i backed up to one of my internal ones, but now when i try to change the settings it wont let me select the drives to back up and it says (Missing) 0 bytes free space 0 bytes total space. and it wont let me check the box next to them to select them.
Anyone have any idea what i should do?
