I got a couple of these errors the last couple nights. We use Win2003, NW 
7.4 SP1, and always have. All the media therefore has always been written 
to by Win2003, it's not like we're mixing media that had been written by a 
Unix system.

NetWorker media: (notice) Volume "910088" on device "\\.\Tape3": Block 
size is 32768 bytes not 131072 bytes. Verify the device configuration. 
Tape positioning by record is disabled.

Now, I did have to delete and re-add the library, because the device name 
changed (see recent thread on this topic). However, NW automatically 
configured the drive; I never specified anything about blocksize. And the 
Windows blocksize shouldn't change - it should be the same as it was in 
the past. I ahve other tapes of this same vintage that are not reporting 
this problem (i.e., these are all tapes that came back into rotation after 
our standard 2 month cycle). So the block size on all 10 tapes that were 
used last night should have been the same, yet only 2 tapes are the ones 
complaining.

Since these were clone jobs, it meant I had to manually start a couple 
clone jobs before I went to bed last night, which is not exactly what I 
wanted to do with my evening. :-) 

Thoughts? Causes, preventative measures for future?

Thanks
