On a request like this it would be good to know the
OS you are using as different OS's have different tools.
I would consider mt "status" rather than "load".
You might even want to rewind before dumping.
The mt man pages on Solaris and SuSE say:
EXIT STATUS
0 All operations were successful.
1 Command was unrecognized or mt was unable to open the
specified tape drive.
2 An operation failed.
So nearly any mt action seems like a good choice.
