That's not correct for DLT. Writing a block at BOT will change the density for the remaining writes. Writing to any other location on the tape will continue using the existing density. So a simple 'mt rewind ; dd if=/dev/zero of=<correct device> count=1' should set the density. See section 2.4.2 in the DLT7000 product manual http://downloads.quantum.com/dlt7000/dlt7000productmanual.pdf It could be that it's an old tape that has never been changed to the correct density, but my bet is that something else is going on. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
