↓↓↓ Complete description, time index and links below ↓↓↓

Two more dead Western Digital USB hard disks fell into my hands. They looked identical, but one said “My Passport” and the other “WD Elements”. Wondering if there were any differences inside, I took them apart.

00:00 Intro – from the outside they seem to be identical
02:07 Cases – real easy to open, containing the same disks
04:50 Controller – all of the chips identified
07:37 Disk – getting a little destructive in between
14:07 Motor – it’s a BLDC with a center tap
17:14 Wrap-up – forgotten rubber bumpers and group picture
