When I set hdparm -S it tells me it sets the option and what the number means. hdparm -I says the Power Management feature is set (btw it is still set when I set hdparm -S 0). So far so good. But even when I unmount the drive it doesn't spin down, at least there's nothing in the syslog and hdparm -C says it's still active. I can unmount the disc, set it to sleep with -Y and when I mount it again syslog says ata2.00: waking up from sleep Nov 25 16:00:01 media-server kernel: [ 1055.621588] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 Nov 25 16:00:01 media-server kernel: [ 1055.621664] ata2.00: waking up from sleep Nov 25 16:00:01 media-server kernel: [ 1055.621738] ata2.00: hard resetting link Nov 25 16:00:01 media-server kernel: [ 1055.938034] ata2.01: hard resetting link Nov 25 16:00:02 media-server kernel: [ 1056.414344] ata2.00: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Nov 25 16:00:02 media-server kernel: [ 1056.414360] ata2.01: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Nov 25 16:00:02 media-server kernel: [ 1056.438445] ata2.00: configured for UDMA/133 Nov 25 16:00:02 media-server kernel: [ 1056.446699] ata2.01: configured for UDMA/133 Nov 25 16:00:02 media-server kernel: [ 1056.446711] ata2: EH complete Seems ok. But nothing is syslogged when I mount it after setting hdparm -S 1. Any other ideas? Maybe this is important: I use Squeeze, 2.6.32-5-amd64, hdparm v9.32, the drive sdc is a WDC WD20EARS-00MVWB0 and the mainboard an ASUS P7P55D. There are four SAMSUNG HD154UI discs in a mdadm raid5 array but I think they more complicated to setup because of mdadm. The idea was to send them to sleep too but because of mdadm it seems to be a better idea to look at them later... -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
