How to extract a filesystem from a disk image
# sfdisk -l -uS image-file Disk image-file: 0 cylinders, 0 heads, 0 sectors/track Warning: The partition table looks like it was made for C/H/S=*/255/32 (instead of 0/0/0). For this listing I'll assume that geometry. Units = sectors of 512 bytes, counting from 0 Device Boot Start End #sectors Id System image-filep1 32 261119 261088 83 Linux image-filep2 261120 4267679 4006560 82 Linux swap / Solaris image-filep3 4267680 142253279 137985600 83 Linux image-filep4 0 - 0 0 Empty
Now, suppose you want to extract partition number 3. You can see that it starts at block 4267680 and is 137985600 blocks long. This translates into:
# dd if=image-file of=partition3-file skip=4267680 count=137985600
Now, peeking into the contents of the partition is as easy as:
# mount -t ext3 -o loop partition3-file /mnt/hack
