You should use -m dvd only in case your crtypdev1 device is DVD. -m dvd prepares UDF filesystem layout and alignments for DVD media. So you should not use -m dvd for hard disks. Also DVDs have block size of 2048 bytes and UDF mandates that medium block size matches UDF block size. Linux versions >= 4.11 do not have problems with it, but other operating systems enforce that rule. So you should not use -b 512 for DVD medias. -- Pali Rohár pali.rohar@xxxxxxxxx
