I am having a similar issue. I have a windows 2000 master and a pair of sun
480's with 8 LTO2 drives shared between them. I get External Event caused
rewind error and the tapes get frozen or the drives go down. I didn't have the
problem unti lI upgraded to 5.1 MP4. I have gone over the entire configuration
and cannot find a problem. 

Has anyone else seen this and found a resolution?
