Restore files from "dd" image

Sorry to reply on this zombie, but I cannot resist. To mount this image you have to use the "offset" extension. Check the man page. If you run fdisk -ul [imagef.ile] on the image you can grab the partitioning information and use the start block = to the offse.

Almost forgot, you have to take the block size x the number of blocks, so if it is 512 like default, just take the start block x 512.

example:

fdisk -lu sda.img
mount -o loop,offset=1048576 -t ext4 /backup/sda.img /old

Did you read the whole thread before posting? Does your post add anything to unSpawn's post #8, above, in this thread?

It turns out there is another solution to this problem, which I have used; kpartx. There once was a very nice blog article with a perfect recipe for using it in this application. I cannot seem to find it at the moment, and the rest of what I can find isn't very illuminating. It is exactly the right tool, though, and I've used it a few times on a disk image dd'd from a multi-partition SD flash card.

I wrote about kpartx here and here aprox half a month after I made my previous post in this thread and there isn't really much more to using the command than that.
