I have a lot of DLT IV Tape Cartridges which were used and written to in DLT 4000 drives.
Now I have a DLT VS 160 drive, which uses the same Tape Cardridges but I can't write onto them.
Searching the net I found only hints that tapes must be unformatted for usage in VS 160 drives, so they can format these with their higher native density.
Is it possible to "force" a reformat of such a tape in a VS 160 drive or is my only option to buy or lend a bulk degausser?
