I'm running Networker 7.4 on a Sun/Sparc Solaris 9 server, with a SpectraLogic 
T50 jukebox, two LTO4 drives.

I want to verify what blocksize Networker is actually writing to the drives - I 
believe it's 64kb. These drives are much more efficient at 512kb.

I manually set the drives to 512kb, but (admittedly only one try) they couldn't 
read a previously written to tape. 

If I want to change to 512kb blocksize, will I have to relabel all the tapes? 

Also, I believe I read somewhere that Networker always writes the labels at 
64kb and the backup data at something else.

Just beginning this investigation, and am looking to skirt red herrings.

Thanks.
