Thanks for the dump. It contains all the info I need. What happens is that your
drive reports that the last recorded block on the media is 2295103 (in 2048
bytes sized blocks) but apparently it's not able to read anywhere nearby before
it. Finally we find the anchor block in block 256 (either the media is open or
it is not standard compliant) but we check all the blocks near the end of the
media earlier and that's causing troubles to your drive. I've checked the UDF
standard and it seems we are allowed to try block 256 first and use it if it's
OK but it needs larger code modification because currently we first check which
of the all allowed blocks look reasonable and only after that fully verify
which blocks are completely fine. So even if I put block 256 in front of the
sequence we'd try reading blocks near the end of the media anyway. So stay
tuned.
Tejun, I'm taking the bug since this really seems like UDF which is making
difference. Thanks for help.
