Putting harddisk to sleep... and keeping it sleepy
Hello, ive got a machine which i use as a media center, running kubuntu (gnome is also installed). However, when im not using it it would be very nice to keep my harddisks powered down - I know how to do this with hdparm, but they always spin up again after like 5 seconds.
What i have tried:
laptop_mode start - this makes the harddisk turn off alright, but they still spin up after 5 secs.
unmounting all volumes from the discs i want to put to sleep - still same problem.
-- I have also observed a constant buzzing sound from the harddisks, which lasts 10-30s and reappears after 10-30s. Its sort of a writing sound, but at a much lower volume, kind of feels like it wants to write something but its afraid of something hehe.
