Re: [K12OSN] OT: hard drives and magnets



sounds like an accidental (or maybe not so accidental) reformat of the
harddrive

I've tried to wipe hard drives with those BIG electromagnets with the
drive out of the machine in my hand and still couldn't get it wiped that
clean (was trying to destroy em before throwing them away)
