I'm not sure I have a good answer, but a parity error usually means something bad happened between the disk and the controller. The cheapest solution would be to replace the cable, and see if the problem persists. You may also want to search the -stable and -questions archive for more on what others have done with this type of error. Recently, I had a friend run into this problem. He fixed it by moving his ethernet card off the IRQ that SCSI controller held.
