Today, I'm sharing a picture of a failed Seagate 5TB Hard Disk Drive. This model is ST5000DM000. This is how it looks internally:
The drive failed prematurely. It looks good. The heads are parked correctly, and it spins up. The problem seems to be in the firmware are of the disk, as it seems to seek but after that, it does a 5 soft clicks before the SATA to USB adapter begins to blink. This HDD was taken out of the external enclosure and was from the Seagate Expansion series.
