To make it sleep until needed I've added atacontrol spindown ad5 60 into /etc/rc.local, but it turned out that this won't affect the drive until it is touched in any way. For example, if I do `dd if=/dev/ad5 of=/dev/null bs=512 count=1`, drive will spindown in 60 as it should. If I add it to fstab, it's also spun down. But until it is touched, it wont. % sudo atacontrol info ata2 Master: ad4 <ST3300622A/3.AAH> ATA/ATAPI revision 7 Slave: ad5 <ST3300622A/3.AAH> ATA/ATAPI revision 7 % dmesg | grep ata2 ata2: <ATA channel 0> on atapci0 ata2: [ITHREAD] ad4: 286168MB <Seagate ST3300622A 3.AAH> at ata2-master UDMA100 ad5: 286168MB <Seagate ST3300622A 3.AAH> at ata2-slave UDMA100 % dmesg | grep atapci0 atapci0: <Marvell 88SX6121 UDMA133 controller> port 0xec00-0xec07,0xe880-0xe883,0xe800-0xe807,0xe480-0xe483,0xe400-0xe40f mem 0xfeaffc00-0xfeafffff irq 16 at device 0.0 on pci3 atapci0: [ITHREAD] ata2: <ATA channel 0> on atapci0 >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
