I've seen this with tape drivers before. You can have a "non-rewinding"
driver, or a "rewinding driver", and others. They all can use the
same tape drive, if the drive supports it. So I'll bet there is some subtle
difference in them which the software developers use to their advantage.

Probably one is "writing" and the other is read-only, or something like
handles buffering different, etc.
