You can mount partition from a dd image of the disk if you know the offset of the partition.
I have an image of the entire disk created using dd. The disk structure follows:
kent@cow:~$ sudo fdisk -l Disk /dev/sda: 750.1 GB, 750156374016 bytes 255 heads, 63 sectors/track, 91201 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x000b8508 Device Boot Start End Blocks Id System /dev/sda1 * 5 90872 729929303+ 83 Linux /dev/sda2 90873 91201 2642692+ 5 Extended /dev/sda5 90873 91201 2642661 82 Linux swap / Solaris
The image was created using:
dd if=/dev/sda of=image750.img
How would I, if it is possible, mount /dev/sda1 from the image so that I'm able to read the contents?
It's not an option to clone the HDD again, I know how to do it if I had only cloned the single partition by itself. I hope it's still possible with the current image.
3 AnswersLoopmounting is only part of the answer.
Look at http://wiki.edseek.com/guide:mount_loopback#accessing_specific_partitions_in_the_image for help on specifying the partition. I think
mount -o loop,offset=32256 /path/to/image750.img /mnt
will work for you. but you really should read the mentioned tutorial.
the offset looks wrong; that corresponds to a partition start of 63 (<i>63 * 512 = 32256</i>). the offset in baumgart's answer looks more correct for this situation. the link is a good reference, but it'd be a better answer if you took the time to summarize the steps or commands needed for this procedure. thanks!
You've got the first part: fdisk -l to find the start offset. Take that number, multiply by 512, and you'll get the offset option to mount. So, for sda1 in your case, 5 * 512 = 2560. Then run the mount:
mount -o loop,offset=2560 -t auto /path/to/image.dd /mount/point
