ok, here is a quick list of what to do:
1) connect your spare disk (USB) (not the bad disk!!!!!) and as root
check what device id it got (tail /var/log/messages) look for detected
partitions there or do
fdisk -l /dev/sdx where the sdx is what you found from /var/log/messages
2) As root Mount the disk:
mount /devsdxy /mnt
(where y is the partion number you want to mount)
if mounted goto 3
This may fail if it is ntfs
2B) If it fails format the disk as ext4:
mkfs /dev/sdxy
and then mount it as under 2
3) I assume here that your bad disk is already connected (as sdz check
first what the real name is)
dd if=/dev/sdz of=/mnt/image.dd bs=1M
This will copy the contents of your bad disk to image.dd
4) just to be sure, make the image read-only
chmod uog=r /mnt/image.dd
5) install testdisk from the epel repo
yum install testdisk
6) now run photorec from a directory where you have sufficient space,
ifg your usb disk is big enough do it there (hint create a sub-directory
mdkdir /mnt/recover
cd /mnet/recover
but any dorectory would do
photorec /mnt/image.dd
The copy to an image is not really required, but better safe then sorry
I have written this from
