Please help...

I have a project with a number of mirrored disks. I mirror them by running
fdisk, mkswap, mke2fs, and cp -ax to the new disk. The disks are Maxtor
DiamondMax Plus 8 40GB disks. I let the BIOS autodetect them, and then I let
linux do the same, so i am not giving any special parameters for the fdisk
to create the partitions. I am running Debian Unstable, and using Lilo to
boot. The board that we are running on is a custom made board, running with
an Advantech ETX, and our own motherboard (ie none of the hard drive logic
or controlling chips were done by us, but the hd cable does connect through
our board to the PMC connector on the ETX).

On some of the disks I get errors that make me think there is a physical
problem:

end_request: I/O error, dev, 03:02 (hda), sector xxxxxxx..

I have also gotten 'DriveReady SeekComplete Error' errors, but I don't have
the exact error to give at the moment.

I have on some of the disks ran e2fsck with a non-destructive physical
check, and I have found no errors. What else can this be? Is there a more
intensive way to check the disk, can this error be due to a cable? Might
this be due to bad parameters when creating the partitions? I have been
trying to deal with this error for almost half a year now, and I have
searched the internet quite a bit, but I have not found anything which has
explained this for me.
