RE: Question about spun-down USB disk

OK, that is odd.
The timer on all my disks report 60 (I assume those are seconds).

I'll keep an eye out for that error and see if I can find out where it came
from.
If it is not the spin-up time, I must have accidentally pulled a (USB)
cable. 
(From what I can see in the logs, I just plugged in a different drive before
the drive failed)


I thank you very much for the hint, it was exactly what I was looking for,
  and I apologoze for my <rant> from earlier on.
  (I assumed it was set to 1 or 5 seconds).

Try the /sys/bus/scsi/devices/*:*:*:*/timeout attribute.

Of course increasing the timeout isn't a particularly sophisticated method
to solve the issue, but simple enough to try.  The default timeout is 30
seconds: linux/drivers/scsi/sd.h::SD_TIMEOUT.  Can an HDD really take longer
than that to receive a request when spun down, spin up, execute the request,
and return status?
