I hope some one can tell me if this will work
can I do a backup and put it on a external harddrive ,,then change internal harddrives and put it all back on the internal drive


the reason I want to do this is the internal drive is making noise .. so I think it is on its last leg ...
will I have trouble doing this


?
It is a w31o7 desktop pc with a 100 gig drive
how big of drive can this thing hold
Im not the best with computers but have changed drives befor
thank you all for reading my post
