Copied files from my 'empty' partiton last week with Photorec and expert settings. Set sector size to 4096, as suggested by e2fsck and hdparm. It took only several hours instead of 3 days to copy the files. In the meantime, nothing seems to have changed: testdisk still does not see any files and ...

Crap. I wrote the partition structure to disk and went for the superblock thing.

It gives me this:

Disk /dev/sda - 736 GB / 685 GiB - CHS 89539 255 63

Partition Start End Size in sectors

Linux 31821 1 1 89538 78 56 927228512
superblock 0, blocksize=4096 []

I set the cylinder boundary to 'no' and allow partial last cylinder to 'yes', but I'm getting the same result: Testdisk sees the partition, but no files.

I suppose I should write the table anyway and try to recover with the ext4 superblock thing. Or is there still something else I can try?

Thank you for your advise, Fiona :) I haven't yet written the table to the disk yet, since Photorec at the same time is still copying over files and I want to be sure at least something is saved before I do anythning else to the partition.

As soon as it's finished I will reboot and run Testdisk ...

Changed cylinders, and that makes my lost partition appear in Deeper Search, and I can select it as primary (as used to be the case). But on enterng P to list files, its says there are no files because the partition may be damaged.

The good news is that I am now able to restore it. I'm going to ...

I've found it, I believe. I had been struggling with this problem all day and it had become the middle of the night (or early morning, rather). It's so simple I overlooked it, thinking too complicated.

If I'm correct, it's just adding 1 to the number of the last cylinder of the lost partition, so ...

Hi,

While re-installing my system with a Ubuntu derivative I decided that my old partitions could be slightly different than before. I made a smaller / directory, removed swap and made a new one at the end of the root partition, and wanted to keep my /home intact. Stupid enough, I wanted to resize ...

OK, I just recovered everything! Everything! Not a single file was left behind!

For some reason, I couldn't do it the first time. But it's all been recovered now!

Thanks anyway for your attention, Fiona .

I've learnt my lesson: I'll do more backups next time...

TestDisk is the best software in ...
