Can you post the output of dmesg after a boot, so we can see which driver is being used? I assume the new Libata stuff, but maybe you can also turn on debugging in there as well. Stuff like SCSI_DEBUG (in the SCSI menus) might show us more details here.
Also, have you tried a new SATA cable by any chance? That's obviously the cheaper path than getting a new disk...
Good luck, John
