When I say "in your hard drive", I mean that quite literally.
We are destroying some drives for a medical customer. Since we do not have the proper SCSI card to actually connect the drives, we’ve decided to physically destroy the drives. One of them had a stripped screw, and we ended up folding back the metal cover over the drive platters to get access to them.
Amazingly, when we flipped back the cover, we saw that one of the drive platters had a large X written on it with a black marker! See the attached photo.
That’s the strangest thing I’ve ever found *in* a hard drive.
