Is there any reason that I should have trouble doing this?

What OS, and how are you trying to read it, what format is the tape in,
how did you create it, etc.?
Are you trying to read it as file structured, or raw?
Was it written with the same tape drive you are trying to read it from?
No.
Differences in the drives
compression method
density
abaility to handle >90m tapes
Yes (or No)
Dirty heads.
Block size > than the PDP11 software can handle
Different format (DOS vs. ANSI vs. UNFORMATTED)
Badly written tape (software failure)
