It even could be a crappy terminator. if your disk system is running at ultra320 speeds, you might go into the controller BIOS, and set all targets for max 80M transfer/sec, which is ultra160 speeds, and see if the errors persist. I've run into several SCSI backplanes that are marginal at 160M xfer/sec (U320 speeds), but work fine at U160 speeds.
