I duspect it's *all* ATAPI tape units. Mine (Conner) is quite a bit older than the other (Seagate) one that began this thread. And ide-tape has no problem with either drive. Perhaps a whitelist rather than a blacklist here. Meanwhile, my old Conner tape unit is several hundred miles away from me at present. Cheers
