I don't know how to programmatically check that the data blocks in that 
ISO are valid (by which I mean "match the original"). For backup 
savesets then BACKUP/ANALYZE is at least a starting point and the 
default is to write savesets with /CRC and to check the CRC on read. For 
DECW$BOOK stuff, I have no idea how you can be confident that it is 100% 
correct. Then again, it's just text you're going to read (line the 
[.LINE_DOCS] stuff) so I guess it's not hugely critical.

Plus all the stuff I've recovered so far has at most 4096 missing bytes 
I think, which is 8 blocks at most. So the odds that you'd hit something 
bad are quite small.
