   It's been done. I just bulk-erased a couple of TK50 tapes which had
been written by a TK70 drive so I could use them in a TK50 drive again.
Long ago, I wrote a few TK50 tapes in a TK70 drive and had no problems.
I always use BACKUP /VERIFY.

   The rated capacity of a TK50 is 95MB, and that of a TK70 is 296MB, so
I'd say 3X is closer than 4X. The TK50 tapes can be read by either
drive type, but it's slower, and you need more tapes that way. What's
more important to you?

   Not to sound ignorant, but "BUP"? "/VERIFY:ONLY"?
