I've got a DLT 4000 tape drive and I've got some DLT IV tapes, however they were last used in a DLT 7000 drive, so they've been formatted at a higher density. I'm trying to convince Linux to erase them, using mt -f /dev/st0 erase. However when I do that the tape goes for a bit then I get an I/O error. Does anyone know how to fix this?
