After playing with the drive and checking the log, the DRQ+ERR problem only happens when the tape drive is doing REQUEST SENSE. Also the DRQ=1 ERR=1 situation only happens when the tape drive wants us to transfer the CDB, not the data. It looks like the ERR=1 here is the residue of the previous command/error: After an error and receiving the next PACKET command, the drive actually wants the host to transfer the CDB of the next command (i.e. request sense) by setting DRQ=1, but somehow it forgets to clear ERR to 0... Maybe we can ignore the ERR bit if the command is REQUEST SENSE.
