tried the above:
[root at localhost djyb]# hdparm -B 127 /dev/sdd
setting Advanced Power Management level to 0x7f (127)
HDIO_DRIVE_CMD(identify) failed: Invalid exchange
[root at localhost djyb]# hdparm -Z /dev/sdd
disabling Seagate auto powersaving mode
HDIO_DRIVE_CMD(seagatepwrsave) failed: Invalid exchange
I don't understand why.
by the way,
I switched to my fc11 installation and it also kept restarting.
now, in some point auto mount stopped working for some reason and I was asked
for my root password to mount the partitions, and from that point on
everything just worked perfectly.
my assumption then is something in the auto mount process is different then the
and that along the way something in the hdd (or auto mount) itself changed
since the problem occurs in both installations.
using kde 4.4.2 in both installations.
in dmesg I see lots of I/O error messages.
I really hope the disk is not lost, it's 500GB of my favorite TV series and
