I'm trying to do a restore, and I am seeing messages on the NMC about 
"media error, Recorded Entity Not Found", and then I see errors about the 
blocksize is 32768 not 131072 bytes (which is odd, since this is the same 
server and hardware that created the tape ... (altho it may have been 
Win2003 when the tape was created, and is now Win2008). Then I see CRC 
errors ...

I never (deliberately) changed the blocksize, so this is news to me ...

I was able do a "nsrck -L7" from this tape, to rebuild the index that I 
want, but can't restore the actual data.

How best to resolve this? Not knowing when the blocksize changed, I don't 
want to set it to something that will make more current tapes unreadable 
(this tape is from 2010-03). Is it possible to specify the blocksize on an 
as-needed-per-job basis? (I'm assuming I can only do that from the command 
line).
