I have had problems similar problems. My records on this are not entirely clear. Possibly it was with the VAX emulator trying to install VMS 3.0 from a virtual tape of BB-D782E-BE. In that case I know I could not use the TQ simulation and had to use the TS emulation instead. But that could be because the TK50 came out after 3.0, I really can't remember now. I do remember though getting some sort of bad tape error which you would not expect to get from a virtual tape, whether that was with the 3.0 tape or something else though I am not entirely sure, sorry if that is not a lot of help.
