I'm using a seagate ST32000542AS drive connected to the ICH7 controller of my d945gclf2 motherboard.
When accessing the disk i'm getting errors and the drive speed is way to slow.
I tried to disable NCQ, but that seems not to solve the problem.
the drive is formatted as ext 4 and mounted from fstab
Code:
/dev/sdb1 /sg ext4 rw,noatime 0 0
dmesg error:

hdparm -tT /dev/sdb
Code:
/dev/sdb:
Timing cached reads: 1080 MB in 2.00 seconds = 539.48 MB/sec
Timing buffered disk reads: 34 MB in 3.11 seconds = 10.94 MB/sec
What can I do to get normal speeds (w/o errors) and the drive in udma 5,6 or7 mode.
