After some strange errors inside a vm I realized that a ram module was damaged, so I stopped the system, changed the module but when I try to mount the file with

mount -o loop -t ext2 vm-400-disk-1.raw tmp/

I got

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

Do you know a software to try to recover data from raw files ?

Best regards
Fabio

Hi,
your vm-400-disk-1.raw is an image of an hdd - with MBR and partition table. You can use kpartx to create loop-devices for the partitions, which are mountable (if not lvm).

Thanks very interesting, I tried to retrieve the information about starting sector etc.. with parted but it gave me an error:
Error: / var/lib/vz/images/vm-400-disk-1.raw: unrecognized disk label

so I thought to see the information using fdisk from a backup that I restored, but the mount command still not work.

I also tried the testdisk utility but without success.

thanks anyway
