What the drive is actually complaining about is, that the driver mixed tagged and untagged commands, which is not legal. But I'm sure the driver didn't do that, so the drive must be wrong :) > This snippet came when I tried to format the drive... This message is for example generated by some IBM drives, when they receive a command that can't actually be executed simultanously with any other command (eg. START_STOP_UNIT, perhaps also FORMAT) and this command is sent with a tag. > Any clues ?? Yes, sure: # ncrcontrol -t 6 -s tags=0 Let me know, whether that cures it for you ... Regards, STefan
