Last year i had two 160 gig hard drives set as slave and master ( c & d ),
used c drive for Win xp and d drive for all my mp3`s video`s, pictures and videos of my Grand daughter etc, etc and ran KILLDISK.EXE on the c drive and went to bed.
Next morning i checked the machine and KILLDISK.EXE had finished c drive and wiped d drive as well!
Lost every single thing but using some recovery software i managed to get back 120 gigs of my d drive stuff back. Thank you Ontrack Easy Data Recovery Pro!
