Mounting a disk clone

I wasn't sure where to put this thread but since i use ubuntu for data recovery, I figured this is the best place. So, a friend passed me a 250G Western Digital hard disk the other day and said that his client needs to get her pictures off it. the problem: windows says it wants to reformat the system. so i put in my linux disk and had a look.

when i ran dmesg as root shortly after connecting the drive it gave the output in dmesg.txt i attached

I looked at the original drive with fdisk -l. I have made an image that I will be working with.

I had the same output when i used sfdisk on the image.

mount -o loop to /mnt fails it wants me to specify a filesystem and when i do it spits out a dmesg tail error.

is there anything else i can try like specifying an offset?

you should have FAT32 support.

/dev/sdb1 should be mounted as the FAT32 filesystem vfat

See:

* did you try without option ?

* and for recovery maybe you can testdisk tool
TestDisk Download - CGSecurity

best lucks

root@arumator--net:/home/arumator# mount -o loop /media/250189482C661005/recovery_image.img /mnt -t vfat
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so


I need to mount the image sorry if i wasn't clear. i currently don't have the drive on me if I try mounting the image without the -o loop option it says its not a block device. this is the output from the dmesg | tail
root@arumator--net:/home/arumator# dmesg | tail

try this
Code:
losetup -o32256 /dev/loop0 /media/250189482C661005/recovery_image.img 
mount -t vfat /dev/loop0 /mnt

How did you create this image? Is it one big image with all the partitions in it, or separate images for each partition?
