I have figured out how to read the filesystem type from the superblock.... Looks like superblock on ext2 and ext3 starts at offset 1024 for a length of 1024. The ext2 magic code is 2 byte code ( EXT2_SUPER_MAGIC of value 0xEF53 ) . So, I dd(1) 2048 bytes out dd if=/dev/sda2 of=/tmp/2blocks bs=1024 count=2 I then use od(1) to and read 2 bytes from offset 1024 + 53 (some magic offset where fs type is)=1080 od -x -j1080 -N2 /tmp/2blocks 7b5a This is not oxEF53 which is the ext2, ext3 FS type. hence mount(1) can not work with it. Looks like this product (the one I am cloneing) vendor is playing FS type change game. Ok, I'll change it to what I want and then change it back. So I rolled up a handy dandy perl script to change FS type on the first superblock. And mount still fails. Do you know if mount(1) checks all the superblocks to make sure they are consistant? I am almost there to crack this case.
