Ouch!
That sounds like a common type of problem, namely single point of
failure on alignment. I think I've heard of the same for floppy drives too.

I would also like to confirm that your drive can also read tapes from
your friend's alternate drive.
I'd really prefer if it was a trio of drives. But that's even more
expensive / unlikely / difficult to achieve goal.
