This is what they look like inside, if you’ve ever wondered!
I’ve had a stack of many SCSI, IDE, SATA, SAS disks on the shelves for many years, ranging in sizes from 40MB, 9GB, 36GB, 72GB, 146GB, 500GB, 1TB and 2TB, time to test them all. Out of 50 SATA drives, 6 had failed just because they had been sitting on the shelf doing nothing.
I’ll strip them down, and use the spinning platters, as bird scarcers for my allotment, to keep the pigeons at bay! It takes me 30 seconds to strip them down and remote the platters, and then I’ll shuffle the platters, and string them on my allotment, that’s stops my data being recovered!
This SATA hard drive, the heads have crashed into the platters, and started to score them, see here

Here’s a single platter

here’s a short video of the inside of a hard drive, with the cover removed, with crashed heads.
