Tape to Digital TZ88 20/40 GB DLT

[Tore Lovlien]

I got an old backup streamer from my company, but unfortunately with only 2
tapes of CompacTape IV. There is a lot of tapes with software upgrades, and I
wonder why I can't use these? They looks the same, but the front of TZ88 say
write protected, even if the tape write protect slide is off. Thank you.

Inspect whole the casing of writable and write-protected tapes, mm by mm, to see if there're differentces: any additional holes, or closed/inexistent holes. If you'll not find any physical differences then I guess write-protect mark is written on the tape and you may not do anything with it
