Fixed the Seagate 7200.11 hard drive with the Bus Pirate

Seagate Fix 036-W600

Bill Farrow fixed the Seagate 7200.11 hard drive firmware BSY bug with the Bus Pirate:

I quickly diagnosed the problem down to a dead HDD.  A quick google search later and I discover that I have been hit by the well known Seagate Barracuda 7200.11 BSY bug.  Too many power cycles on the drive and it stops working.

Using the following DIY guide, I was able to recover the disk drive by connecting to the diagnostic serial port on the drive using my Bus Pirate.

Via Twitter.

    I want to learn how to do this.

    Just did this myself with a 5200.3 (st9160821as) that had a false-alarm SMART failure based on “start/stop count” (no bad sectors, no read errors).

    – Connect ground, MISO, MOSI pins to the drive – TX/RX pins are the first two in towards the SATA connector. Ground is the third pin. TX/RX are subject to trial and error – if one doesn’t work, try them the other way around. Connecting the pins is the hardest part.
    – Connect to the Bus Pirate (115200 baud, as usual).
    – Enter “m” to go into mode, select 9600 baud (!) as the baud rate varies – you may need to use baud rate detection and power-up the drive (don’t need to disassemble it and do the paper trick – that just prevented mine from spinning up properly with the “Z”/”U” commands!) to detect the baud rate.
    – During mode selection, the hi/lo mode (last option) should be “2”, “normal” – not the default.
    – Use “W” to turn on the power supply.
    – Enter “(1)” to activate bridge mode without flow control.
    – Power up the drive, you should see some introductory information from the drive. If not (and you just see gibberish, but you see *something* come up), you’ve got the wrong baud rate. If you don’t see anything, try swapping Tx/Rx pins.
    – “/1” will enter level 1 mode.
    – “N1” will clear SMART data. And that’s it!

    If we are using the level 1 we are enable to view the defect list with N5
