Question 1: Before I get over my head into this WT driver [can we say kluge, boys and girls?], has anyone done any work to get it to a working level?? I looked on agate and sun-lamp, but the driver is the same... Question 2: When dealing with a NON-REWINDABLE tape device, the standard [read "correct"] behavior is for the tape to be left at what- ever location the last read/write was, correct?? It seems that the WT driver want to forward the tape all the way to the end after the NON-REWINDABLE device is closed. I am assuming that is because of a bad driver/buggy code/etc. and not done for some good reason. Question 3: The WT driver uses a very distict IOCTL routine from all the other drivers [well, other mag-tape drivers]. It seems to me that this should be corrected so that one can use the same IOCTL to control the SCSI tape devices AND the QIC-02 tape devices. Are there any reasons not to do this? I have already started this, and with large code plunderings from Julian's SCSI TAPE driver an progressing along nicely. What I have done works -- with the exception of the NON-REWINDABLE behavior that I described above. Question 4: Does anyone have/know where I can get more info on the QIC-02 programming interface?? I probably don't want to do THAT much hacking, but it might come in handy... Any input, ideas and suggestions welcome. Rafal
