I have a Soyo 6ba +IV,PIII 450, Win2k, and two Maxtor ATA66 hard drives. I recently updated the HPT366 bios to v 1.28/the newest HPT366 drivers from the Soyo homepage, and now I am having problems using my ATA66 hard drives. I cannot transfer large files between them or the computer will lock and continue seeking the hard drives. I tried to revert to old bios version and use different driver versions but the problem still exists. Anyone have any ideas? Thanks in advance.
