Is this a one-time error, or at least an infrequent one? If so, it's probably a random data error on Channel A, SCSI ID=6, LUN=0 (a tape drive?). I wouldn't worry about it unless you start seeing multiple errors. In that case you could have a cable problem or a device that needs maintenance. You could check the parity configurations of your Adaptec card and device #6 to make sure they're the same. If you disable parity on device #6 (usually via a jumper), parity will still be generated but any errors will not be transmitted down the cable to the host adapter. --Doc Savage Fairview Heights, IL
