    This section of the SCSI command indicates that the driver is requesting
    what I believe to be device geometry information. Evidently it has already
    determined that it is a non removable storage device. However the drive is
    reporting that the inquiry code of FF000000 is not valid. What I don't know
    is if FF000000 is or is not valid as a SCSI inquiry command.

    This could either mean the drive is bad, which I think is unlikely, or the
    firmware on the drive is not compatible with the driver, which is more
    likely. But why? I don't know.

    I'm also confused as to why the command is 5 bytes instead of 4. Most narrow
    SCSI commands are two 16 bit words. Is this a narrow SCSI disk? What about
    the SCSI bus. Is it narrow or wide?
