I had an ext3 filesystem on my hard disk at /dev/hdc2 with a small 1024 byte blocksize. Now I recorded the whole filesystem on a DVD like this:
dd if=/dev/hdc2 of=/tmp/image.img wodim -dev=/dev/scd0 /tmp/image.img
Now when I am trying to mount it, ext3 complains in dmesg:
EXT3-fs: blocksize 1024 too small for device blocksize 2048.
I guess that's because the DVD sector size is not 512 (like a hard disk), but 2048.
Is there some way to mount this? Without dd-ing the data back to a hard-disk of course, as I know that solution.
