Depends on the type of failure. Is the platter still spinning? Does the Bios see there is a hard drive attached? Clicking grinding noise? Not noise = bad, have someone else do it. Not seen by bios platter not seen = maybe *Try finding an identical drive right down to the firmware on and dates and swap I/O boards. The board could be burned out. I have done the "freeze" trick to get them back. Finally partition/sector failure = Spin Rite and HD recovery *Hiren's boot CD 10.6 has the HD recovery and will attempt to repair back sectors. And something like Undelete if the data was "wiped" Hope this helps Timothy Good
