Bump?

This was a 700gig+ partition. The above shows what I know about it now.

Can you check the size of the LUKS partition ? Is it also only 8 MB ?

Parted Magic reports the disk as:
/dev/sda1 7.81 mb crypt-luks
unallocated 698.39 GB

My present system says:
sda1 7.8 mb crypto_LUKS
sda2 1kb unknown
sda5 243.1 ext2

I hope this is the information that you need. This ...

If you can unlock the encrypted volume, "cryptsetup luksOpen device name", when you run photorec, select /dev/mapper/name.

Thanks for the response!

I can unlock the encrypted volume, but only the first few thousand k show in the mapper. The encrypted volume is about 650 gig.

Several months later, and I still need this information:

My filesystem is mounting only up to a point where it was damaged, a few megs into a several-gigabyte system. Since it is LUKS encrypted, can PhotoRec even "see" the files to be recovered?

Is there any hope of extending the point at which ...

I have an encrypted Ubuntu filesystem that I partially reformatted FAT three years ago by accident. I can mount the disk and read part of the data, but unfortunately not the data that I am looking for. TestDisk was not able to repair the filesystem, and PhotoRec didn't find my data.

My question is ...

Answered my own question. It's in the manual under "Advanced Filesystem Utils".

And TestDisk returns a superblock recovery instruction, in case this fails:
fsck.ext2 -p -b superblock -B size device
Thank you for including this, Christophe! I could have spent weeks figuring this out on my own ...

I have similar questions about when it is safe to write. More examples, showing things that can go wrong and what to do would sure lower the anxiety level!

TestDisk shows my lost partition and gives its correct size. But the P: list only lists a few of the hundreds of directories and files that were on the system. Is there anything more I can do, before using PhotoRec? Does PhotoRec make any permanent changes to the disk?

Also, I don't understand the ...

I think I have the answer from the Arch linux wiki:

# dd if=/dev/hda conv=sync,noerror bs=64K | gzip -c > /mnt/sda1/hda.img.gz
and to restore,

# fdisk -l /dev/hda > /mnt/sda1/hda_fdisk.info

Basic stuff. It allows us to backup to a normal zipped file instead of buying another hard disk to ...

I would like to backup/clone/copy a failed partition to a file under Linux, and be able to reverse the process if needed. Reading the ddrescue documentation, it seems that partitions can only be copied to other partitions, and the dd documentation is ambiguous on this as well. Will this create a ...
