BIOS does not recognize 500GB-disk

BIOS does not recognize 500GB-disk

[Hadmut Danisch]

Hi,

just a question:

I have an older computer with a ASRock K7VT4A Pro mainboard and a VIA sata
controller. 

A 320GB Seagate SATA disk worked pretty well with that board, but now I replaced
it with a 500GB Western Digital SATA, and the BIOS does not recognize that
new disk, allthough I've updated the BIOS to the latest available version.
The disk is not available under Linux (latest Ubuntu, 2.6.20). 

I guess it is a BIOS problem, since the disk works in a different, newer
machine with a newer mainboard. 

Is there any way to have Linux to ignore the BIOS and to access that disk
even if the BIOS didn't recognize it?

regards
Hadmut

Turn off NCQ on the drive, limit to 1.5GBps operation, try again, I have 
the same issue with a new RAPTOR (NCQ) and old motherboard.

Yup, that was the problem. The VIA chipset did not support SATA-II. I
had to set a jumper on the disk to slow it down to SATA-I.
Unfortunately, they didn't tell that jumper setting on the disk's
sticker, and the disk didn't come with a jumper, so it was not obvious.


Thanks and regards

Please post boot dmesg.
