Three issues I've seen...

1) IDE cables.
     Swap and try again
2) DMA set too high
     Seagates seem to suffer the most for me... ***Cautiously test***
the DMA settings, Multiword, and transfer speed settings on hdparm.
3) Drive failure
     smartctl is your friend... It will query the drive to see if the
drive reports having difficulties... What most hard drive testing utils
do.
     Download the bootable CD from seagate to test the drive. It runs
linux, so it should be pretty on the ball.

HTH
