Mount a dd image backup of a RAID drive
I'm trying to help a friend recover a system of theirs. They were running a RAID1 (2 mirrored drives) and when I plugged one of the drives into my Ubuntu 10.04 system I was able to successfully copy their files for them. I also used dd to image the drive as I wanted a backup while I re-build their RAID array.
What I'm wondering is if it is possible to mount this image file? I've tried mount [image file] [dir] and mount [image file] [dir] -o loop. I've even tried using the -t ntfs option but no luck. It seems to be recognizing the image drive as a RAID partition even though when I physically plugged the drive into my computer it had no problems.
Any ideas on how I can mount this correctly?

I suggest you educate your friend to make regular backups, this avoids the need for any of this messing around.
You can try:
sudo mkdir /media/iso
sudo mount -o loop /path/to/
Just change /path/to/

As I mentioned above I tried that already. Here is what is printed in the terminal: mount: unknown filesystem type 'isw_raid_member'
When you used dd to image the drive to this image file that you're trying to mount, what did you do? Did you image the whole drive, e.g. /dev/sdb, or a partition within it?

Ah! You're right I did the entire drive. No wonder it doesn't recognize the filesystem. Is there I way I can mount an entire drive like that in Linux?

I followed the posts on this forum thread and got it to work. Thanks for your help!
Yes, sfdisk -uS to list the partition table and then pass the right offset to the loop mount device is how I do it. Don't forget you can mount most filesystems read-only, ro, to avoid altering the archived image.
