Hi,

My SATA disk (sdb) spins up at every system resume. How could I avoid
that please?

Some details:

- sdb not mounted
- echo 0 >/sys/block/sdb/device/scsi_disk/2:0:0:0/manage_start_stop
- hdparm -C /dev/sdb :   "drive state is:  standby"
- s2ram
- after wake up:         "drive state is:  active/idle"
- kernel message at wakeup: "sd 2:0:0:0: [sdb] Synchronizing SCSI cache"
- when doing "echo scsi remove-single-device 2 0 0 0 >/proc/scsi/scsi"
  before s2ram, sdb keeps sleeping after resume

I need the disk only about once per week. I use s2ram several times per
day, and I prefer that sdb keeps sleeping.

TIA for any hints,
