More info: these are fiber connected LTO-4 drives. The properties of the 
drive where the tape is loaded (all the drives, it seems) at set to 
"handler default" in the properties, under "device block size".

The volume does indeed say "block size 128K".

This is the first time I've seen this. I've never had to set block size 
per drive; I just let it use the default. Do I need to change the drive 
block size, in order for this to work? And do I leave it changed, or set 
it back to "handler default" after the recovery is done?
