Hello all,
I do have a 3TB HDD on my Arch linux for some years now (maybe 2 or 3 years) which is divided in three partitions:
- PTR 1 (EXT4)
- PTR 2 (EXT4)
- PTR 3 (NTFS)
The system itself run outside of this HDD, the partition 1 (PTR 1) was corrupted somehow and I tried to recover the partition, it seems to be badblock at first but I couldn't repair it, so I've tested the TestDisk to re-find the partition.
However in the process I've made a big mistake of not take all attention on the process, by using too many tabs on terminal and accidentally found and saved the partitions however it was not exactly was it suppose to be, then it make the "PTR 2" and "PTR 3" unavailable.
But due to the fact that I had the partitions already mounted I still have access to it normally, but if do reboot or umount it, i'll gonna lose the access to the filesystem.
Here the output of df (of these partitions):
/dev/sdc2 1.2T 937G 165G 86% /run/media/hlechner/PTR2
/dev/sdc3 684G 76G 609G 12% /run/media/hlechner/PTR3
Result of gparted for example:

Hitting ignore again:

As you can see the partitions are different sizes now, and do have two "unallocated" which doesn't have before.

>* Linux 0 1 1 121575 254 63 1953118377 [PTR1]

P HPFS - NTFS 275563 200 30 364801 66 1 1433600000
The result of saving it is what gparted shows in the images above.
So, the important to me now is to repair the two partitions that I had working before (PTR 2 and 3) that I probably gonna lose if I reboot the system.
What do you guys recommend me to do to repair it?
Thanks

what testdisk find if you run it again with deeper search ?

It take a very long time due to HDD speed and the size of it, but unfortunately it find a worst scenario than the quick search with more partitions.
Edit:
Adding some information that maybe is useful:
fdisk:

Partition 3 does not start on physical sector boundary.

The size of this disk is 2.7 TiB (3000592982016 bytes). DOS partition table format can not be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).
