by I was hoping someone could help me out. We just recently got in a PC that
will be running as a disk server for both Unix machines and some Wintel
machines (using Samba). We have 2 8.6 GB drives (Seagate ST38641A).
During the installation of Linux (RedHat 5.1 - 2.0.34 kernel) the system
kept crashing. I finally got the OS installed by tweaking some of the
BIOS settings.
The problem is that once the system was up and running, disk access was
painfully slow (between 0.07MB/s and 0.21 MB/s). I am not sure if this is
a problem with the UDMA onboard controller or not.
I don't know if this is related, but we get the following error message
during system boot:
Jul 7 11:49:09 aardvark kernel: Partition check:
Jul 7 11:49:09 aardvark kernel: hda:hda: set_multmode: status=0x51 {
DriveReady SeekComplete Error }
Jul 7 11:49:09 aardvark kernel: hda: set_multmode: error=0x04 {
DriveStatusError }
Doing a cat of /proc/pci gives (among other things) the following info
about the IDE controller:
Bus 0, device 7, function 1:
IDE interface: Intel 82371AB PIIX4 IDE (rev 1).
Medium devsel. Fast back-to-back capable. Master Capable.
Latency=64.

hdparm -i /dev/hda gives:

If anyone has some ideas, they would be greatly appreciated.
Thanks,
