Comment 3 for bug 555337

additional information: after the drive spins up, the drive state is reported to be standby (hdparm -C).

i) why does the drive change state at all?
ii) why is the disk spinning? Sleep means active electronics, but no spinning.

Furthermore changing the drive state does not work correctly anymore.
1. drive is in state standby
2. after issuing hdparm -Y (sleep) no errors are reported, but the drive is still reported to be in standby and spinning
3. the drive has to be woken up into active mode (e.g. fdisk /dev/sdb)
4. then it's possible again to successfully send the drive to standby/sleep
