Hello,

What is the correct sector size for Blu-rays? The data sector size is 2048
bytes, but the ECC sector size is 65536 bytes. Neither setting gives me an
error in -d mode.
I don't know, but if no errors happen, setting the sector size to 2048
or 65536 does not make a difference because ddrescue reads blocks of
65536 bytes by default during the copying phase; --cluster-size is
adjusted accordingly:
'-c SECTORS'
'--cluster-size=SECTORS'
Number of sectors to copy at a time. Defaults to 64 KiB / sector_size.
Best regards,
Antonio.
