Incorrect.
If you specify F:\ a the only entry in the backup selection list and it
does not exist, you will get a status 71.
If you specify C:\, D:\ and F:\, and the system has a C and D drive, but
no F drive, you will not get a failure.

If anyone is still running one of the affected MP levels, there was an
issue where netbackup would backup directory structure but no data, and
explicitly specifying the drive letters was a documented work around for
that issue.
