Hi Michael,

I have seen this or a related problem on different sites using (always) new 
(2011-2012) overland tape libraries.
The workaround was to label the (blank) tapes on a different server. Does it 
happen with labelled tapes or only blank ones?

If you cannot downgrade,  that may happen because the 1.0.6.3  driver files are 
still on the windows directories. Try uninstalling the 1.0.6.3  driver, remove 
all the 1.0.6.3 files  and reboot the windows machine. That might work.
