ATA Bus error messages on pata_sch

I have tried asking this question here but did not get any response.

I was wondering if anybody here would know about this:

Using Debian 5.0 with 2.6.30 kernel. I see the following messages during kernel boot. Here is the relevant dmesg output:

I just have a single IDE drive attached and the IDE driver that is loaded is CONFIG_PATA_SCH.

What does the above error message mean? Is it very fatal/serious?

pata driver is what should be loading do not worry if it tries to load the sata driver and fails pata is IDE Parallel ATA, Sata Serial ATA so when sata came out we changed the module name to pata. Those new net books us a flash drive but the cable is IDE witch is like your IDE parallel ATA master slave Sata no master or slave the kernel is just loading modules till it gets the right one If your machine has sata ports on the mother board Linux reads the bios and starts loading them but no sata harddrive so it fails.
Just My thought.

according to your log it does not fail it's out put is error. It tries to set the buss at 100 UDMA but that drive a does not support that then it tries to set the device up with 66 UDMA and succeeds on mine I have and old IDE and it goes to 33 udma.
but all is well

it is just reading your bios and device ports

if you think the drive has FS problems run
e2fsck -f -c -v /dev/sda8
