http://forums.fedoraforum.org – I send my hdd to sleep with /sbin/hdparm -S 241 /dev/sd[ab] every day at 8:30 pm. If there's no activity for 30 minutes the drive will enter standby. At 06:00 am I want to change the 30 minutes to 4 hours. But when I enter /sbin/hdparm -S 248 /dev/sd[ab] in the morning both drives spin up. Is is possible to run /sbin/hdparm -S xxx /dev/sd[ab] without waking up a hard disk? Or to detect whether the hard disks are already in standby? (HowTos)
