My friend was trying to install a new hard drive he just got. He used a magnetic screwdriver and came close to touching the hard drives. Now the old hard drive will not boot up, and the new hard drive says "imminent drive failure" on bootup when he puts it in. The new HD is Western Digital, the old one was Maxtor. Any ideas as to what he should do? Do you think the magnetic screwdriver could have caused this? Thanks.
