Hello,
It looks like you stumbled into a change they made in the 2.6 kernel, which
will undoubtely cause a lot of people a *lot* of pain. The change prohibits
a program from opening a drive in read/write mode if there is no volume in
the drive.
If this is what is causing your problem, you can solve it by:
1. Ensuring that there is some tape in the drive befort starting the SD,
and before issuing a "mount" command in the console.
2. Upgrade to version 1.38.0 (you might wait for a Win32 fix if you have
Win32 clients).
