Hard Drive Euthanasia

I euthanized a Western Digital My Passport 1 TB external hard drive (Model WD10JMVW-11S5XS1). It belonged to a relative who passed away, and I was hoping to retrieve important information from it (namely bank account information, a will, and/or an estate plan). The drive failed to mount, but I was able to extract files from it using Disk Drill.

Following data recovery, I attempted to format the drive, but attempts to do so using Disk Utility and Terminal commands were unsuccessful. Therefore, I decided to destroy the hard drive to ensure that data could not be recovered.

Curious to see the inside of the hard drive, I disassembled it by popping off the plastic casing and removing the Torx screws. When I finally uncovered the platter, I bent the read/write head and arm so it could no longer function. I then grabbed the platter with pliers, and to my surprise, it shattered to pieces. I had assumed that the platters were magnetic media similar to floppy disks but apparently modern hard drives have platters that are made of glass or glass-ceramic base materials which are then coated with a thin layer of magnetic material where the data are stored.

I was not wearing protective eyewear, and fortunately I did not sustain any injuries other than a small superficial scratch on my finger. If you ever decide to disassemble a hard drive, be careful! Next time I euthanize a hard drive, rather than taking it apart I might smash it with a hammer instead.
