alarming right now with the lois lerner emails and the six other individuals. if you have a hard drive crash to send it to a repair shop to recoup the hardware failures that happen on the hard drive itself would be relatively easy to do. otherwise if you had software that destroyed the evidence or destroyed everything on the hard drive you would have something that would erase sector bisek tore of the hard drive itself it would make it uncoferl at that point. >> i had external hard drive and dumped a lot of pictures on it. all of a sudden they couldn't recover the pictures. i sent it to the manufacturers they spent three months. instead they sent me replacement hard drive minus the pictures. they said it crashed and unrecoverable is that different. >> not necessarily. in that case they may not have been able to recover it. companies specialize in recovery of data. most organizations that have hard drive failures can send them to these places clean rooms and reassemble the hard drive and fix all the issues out there. most cases can you recover a very similar case, yes.
