Is this a problem with all Seagate DAT drives or just the 24GB >version? Check your manual. It's probably not reading a marker on the tape. DAT tapes have identification holes so the drive can tell what type and density they are. My DDS-2 drive won't write on pre-DDS-2 tapes unless I throw a special jumper -- it will normally only read them. Your drive is probably doing the same thing -- only reading older lower density tapes -- and writing to only the correct (DDS-3?) tapes. ----------------------------------------------------------------------------- Michael L.
