It would be a severe firmware bug or failure of
the media to properly record the correction
mapping of physical records.
I am not really convinced of such a failure yet.

One possibly can disable the effect of Defect
Management by the Streaming Bit of SCSI command
28h READ(12). At least i read MMC-5 220.127.116.11
"If the Streaming bit is set to one, linear
replacements shall not be performed."
One would have to search in the kernel whether
command 28h is used and whether bit 7 in byte
10 of the command can be set.
But i would be astounished if that was the
default with BD mounting resp. with the involved
Also it does not explain why the zeroed block
at address 8 MB causes a mountable empty UDF
filesystem with no error messages in the kernel

Is there any way how after umounting of the
filesystem the content is still not up to date
for subsequent reading of the file ?
