HP DDS3 DAT and DEC Tapes

[Patrik Schindler]

Hello Folks,

I’m having fun time to erase used DDS tapes for reuse. I’ve been collecting those over years. Recently, I discovered that with DEC brand tapes, the drive reports the cartridges to be write protected, eventhough the slider is closed which means, they’re supposed to be writable. I suspect there is a software write protect flag on them.

Any thoughs, hints, advices how to unlock these tapes for overwrite?
