Are you sure about this? I think you are mixing up the 60 MB tapes with
the older 23 MB tapes ( from the 3B2/400 or XM ). To my knowledge the
23 MB tapes were the only cartridge tapes that needed to be formatted
ahead of time. I KNOW that I have written a 60 MB tape on a 3B2/600
and read it successfully on a 6386. In fact, it was the first thing I
tried once I got my hands on a tape drive for the 6386. ( this was using
cpio )
