Teardown: Seagate Barracuda Drive

I had to clean house for an inspection and had several very dead hard drives around, none of which could be sent back for warranty, so I dismantled them.  Most drives are easily disassembled with miniature Torx bits which are readily available from many vendors. (here’s one such set.)

This Seagate Barracuda died in a “normal” way, its SMART data showing increasing reallocated sectors indicating slow-motion death.  Its controller board is quite small:


Almost all hard drives these days use the same Samsung 32 meg cache memory.  LSI is a familiar controller vendor and one of their chips is here.  The ST Microelectronics SMOOTH chip is apparently a motor driver—I’ve seen it in several drives.

The drive lost its warranty due to an external enclosure and a very badly designed SATA pigtail that broke the connector on the drive.  The enclosure had numerous other problems, ensuring that I will not use that make again anytime soon.

Next up, Western Digital, torn apart.

    Do you know how to remove the spindle motor on the Seagate Barracuda? I’m trying to salvage the case and motor to reuse for other purposes.
