Hi,

We have a problem with Networker 7.6.1 running on Windows Server 2003 32-
bit. Jobs not requiring new or recyclable tapes run just fine, but any job 
that tries to take into use a new tape or a tape in recyclable mode, fails 
immediately after trying to start to write data on the tape ("Media notice: 
NetWorker media: (Warning) XYZ123 marked full prematurely. Verify possible 
error on the device \\.\Tape0, advertised capacity is 800 GB marked full at 
0 KB".

I have tried with brand new tapes, recycling/re-labeling old tapes, updated 
drivers for both of our IBM TD4 Ultrium4 drives inside the StorageTek SL-500 
library, tried with both drives Tape0 and Tape1, no difference what so ever.

I'm stunned on where to proceed next, I will try to haunt for firmware 
upgrades on the drives but doubt that'll help any.

Any suggestions are gladly accepted!

Thanks,
Kimmo
