+ 0 Votes Windows Vista not showing external drive. ansiroi 1 year ago First thing first do not format the hard drive under any consideration as you would make the retrieval of your files very hard. I would suggest you purchase a copy of Spinrite at (http://www.grc.com/sr/spinrite.htm) burn it to a CD and boot your computer with it. This program is simply amazing, it is created by Steve Gibson. I feel certain that you should be able to recuperate unless your hard disk is totally toast. Good Luck.
