Doing that is easy if you make a loop device: # losetup -offset 32256 /dev/loop2 harddrive.

If you made this image under duress (due to a failing drive or other emergency), you might have to check and repair the filesystem first. root/harddrive.img on /mnt/loop type ext3 (ro,loop=/dev/loop1,offset=32256) Of course, try mounting the image in another operation system is also allowed. If the problem is related to the image structure, you can mount the image when booted into Safe Mode. A product.img image file is an archive containing files which replace existing files or add new ones. It will repair and recover DMG files on Mac OSX. mount -t iso9660 -o loop path/to/image.iso /mnt/iso. Fire up the mount command and you’ll be on your way: # mount -o ro,loop,offset=32256 harddrive.img /mnt/loop Click Get button to download the installer image on your Mac. Since we need to scoot 63 sectors ahead, and each sector is 512 bytes long, we need to use an offset of 32,256 bytes. You can also view this with fdisk -l: # fdisk -l harddrive.img This means that the filesystem itself starts on sector 63. In the output from file, there is a particular portion of the output that will help you. rawimage/ewf1.

Finally, mount the image using the offset of the correct partition (1050624 512byte offset): mount. The key is to mount the file with an offset specified. /dev/sda3 217909248 234440703 16531456 7,9G Linux swap. Mount: you must specify the filesystem type What if you want to pull some files from this image without writing it out to another disk? Mounting it like a loop file isn’t going to work: # mount harddrive /mnt/temp Harddrive.img: x86 boot sector GRand Unified Bootloader, stage1 version 0x3, stage2Īddress 0x2000, stage2 segment 0x200, GRUB version 0.97 partition 1: ID=0x83,Īctive, starthead 1, startsector 63, 33640047 sectors, code offset 0x48 If you run file against the image file you made, you should see something like this: # file harddrive.img However, you can mount the individual partitions in the image if you know their offset inside the file. Once that’s finished, you should end up with your partition table as well as the grub data from the MBR in your image file. Let’s say you cloned data from a drive using something like this: # dd if=/dev/sda of=/mnt/nfs/backup/harddrive.img Consider a situation where you need to clone one drive to another with dd or when a hard drive is failing badly and you use dd_rescue to salvage whatever data you can. This situation might not affect everyone, but it struck me today and left me scratching my head.
