no-rewind?

[Larry Brown]

I have a single HP-T20i unit and am trying to run amlabel.  Upon running amlabel <set> <tapename> I get rewinding, reading label, not an Amanda tape rewinding, writing label <tapename>, checking label amlabel: no label found, are you sure /dev/st0 is non-rewinding?   Note that this tape was previously used by Tapeware and so has been formatted and has information on it.  Does the tape need to be reformatted in some way?  Or is there something else I’m missing?     Larry
