iirc the drive does not need to be mounted for photorec/testdisk to do its thing.
i can only assume that the same goes for accessing a drive image.
you will need to read the documentation.

edit:
hmm, seems my advice is useless if testdisk/photorec requires partitions.

Thanks for all of the replies folks.

I finally remember the tool that I used before, safecopy.

Here are a couple of links for more info.

http://safecopy.sourceforge.net/

https://sourceforge.net/p/safecopy/d...read/ead2e90f/

I have it running on one of the drives now so lets see how things go

Humm, so more info. It looks like these drives were part of raid array which would explain why I'm having issues. I ended up using dd to create an image of the disk.

Now when I try to mount the image im getting the following error:

mount: unknown filesystem type 'promise_fasttrack_raid_member'

So, time to scratch my head some more to figure this one out.

Safecopy works for regular non-raid disks.

On a full disk image, I usually have sleuthkit installed and run command: mmls -t dos disk.dd for partition offset information, without sleutkit you can try command: sfdisk -l -uS disk.dd.
Typically the first partition would be at sector 63, in this case I multiply that by 512 and get 32256. The mount command I would use is:
Code:
mount -oloop,offset=32256 disk.dd /mnt/image
You can manually mount raid images also.

Never experienced this in over 15 years of dd.
