Hi
I have a bunch of Seagate Barracuda LP 1TB ST31000520AS drives. Some
of them unload their heads very frequently. In 90 days 4 of the drives
are in the 25k numbers (Start_Stop_Count), of their rated 50k.
On the drives that have a high Start_Stop_Count I cannot set APM. If I try:
sudo hdparm --verbose -B254 /dev/sdd
/dev/sdd:
setting Advanced Power Management level to 0xfe (254)
outgoing cdb: 85 06 20 00 05 00 fe 00 00 00 00 00 00 40 ef 00
SG_IO: ATA_16 status=0x2, host_status=0x0, driver_status=0x8
SG_IO: sb[] = {72 0b 00 00 00 00 00 0e}
SG_IO: desc[] = {09 0c .. }
ATA_16 tf->status=0x51 tf->error=0x04
I/O error, ata_op=0xef ata_status=0x51 ata_error=0x04
HDIO_DRIVE_CMD failed: Input/output error
Hdparm -I doesn't show an APM line on the broken devices. I have
attached output from dmidecode, and smartctl -A and hdparm -I on both
a healthy device and a bad device (yes, the healthy device are newer
then the broken one, and are not bought in the same batch, same
firwmare though: CC32).
Kernel is 2.6.30-02063005-generic from
