[Eug-lug] Damaged hard drive

[Quentin Hartman]

I'm sorry to hear that the board didn't work for you. I'll see if we (my
housemate and I) can dig up another one that might make it fly. In the
meantime, try attaching your electronics to the drive you got from me. It
might tell you something. The mechanicals in that are good enough that it
spins up and seems ok, you just get really gnarly I/O errors and what not,
and the occassional weird noise.
