I have tried both 525 MB and 150 MB tape, using al possible devices to match the density. When the driver sets the density, the tape drive always reports 'illegal request'! Skip the density setting and the drive will read and write both tapes fine. Do i have an incompatible tape-drive? Other people have reported the same drive works fine in their system. Adri.
