I had a portable hard drive fail, wouldn't show up as a disk to the computer but would show up on the USB bus. It's a drive I used to keep my GoPro footage on while traveling, and at home it became a backup drive.

Decided to open the plastic case to see if the drive would possibly show up over it's SATA interface, except, hrm, seems the drive is directly USB3. Overall the drive sounds like it's suffering a mechanical failure of some sort, and not really concerned about pulling data off.

Was somewhat surprised to see it have a USB3 micro connector directly attached. Gave me a bit of a flashback to some of the fibre channel drives in the SANs I used to work with.
