I have an at least similar issue on 12.10 quantal: I want to spin down my external USB drive /dev/sdc as fast as possible: in /etc/hdparm.conf:
/dev/sdc { spindown_time = 1 } that works, although I get $ sudo hdparm -C /dev/sdc /dev/sdc: SG_IO: bad/missing sense data, sb[]: f0 00 01 00 50 40 00 0a 00 00 00 00 00 1d 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 drive state is: unknown but after resume from suspend, it doesn't work anymore. my workaround is /etc/pm/sleep.d/20-hdparm #!/bin/bash case "$1" in thaw|resume) hdparm -S 1 /dev/sdc ;; esac and that works, anyway, spindown settings shouldn't get lost on suspend/resume in the first place.
