(Btw., disktab should probably completely go away.) True, it isn't the error I would expect if I were attempting to write to a non-existant block. But it passes the ROM BIOS's test; and it seems to be happening consistantly at the end of the newfs. (For a given partition, it always occurs at the same point in the log output. The reported CDB info changes slightly; but I don't know how to interpret that, so I don't know if it is significant.) And even if that isn't the problem, I'd still like a working disktab entry for that drive. > Parity errors heavily smell like a cabling problem, which becomes more > apparent when you drive the bus at full speed, while the host adapter > formatting probably runs at a lower speed. I only have two devices on this HA. The first is an Exabyte EZ17; which has been working without problem for several months. The other is this disk I'm having problems with. I always try to get high-quality cables. I didn't try formatting, just verifying. Can you suggest any good tests to run from within FreeBSD to check this out?
