TestDisk won't detect partition, but PhotoRec does

Question

I have a small problem, I accidentally formatted one of my drives in Windows.

PhotoRec finds the partition, but Testdisk doesn’t.

Help would be really appreciated.

EDIT: It finds the partition when partition table type is "None"

Did you press Enter on Testdisk when it got that far then select Deeper Search to see if it can find your old partition? — Terrance, Aug 13 '17 at 22:03

I did try a deeper search. Didn't find anything. I've read through that link as well. — Kim André, Aug 13 '17 at 23:33

OK, I was able to fix it.

I went to superblock while in non-partitioned mode. and then it just told me to use a command, here’s it:

fsck.ext4 -p -b 163840 -B 4096 /dev/sde

in case anybody from the future reads this. 153840 being one of the superblock numbers, 4096 being the size and /dev/sde being the drive.

Actually tools like these you mentioned are using base commands and files . First command I suggest to use is fdisk . It's powerful oldschool command .

$ fdisk /dev/sda

This will give shell . Try p to show your partition . Also you can use files in proc directory

$ cat /proc/partitions

This will show all partition that Kernel will care of and command partprobe can regenerate this file . some cases you can not find your partition anymore. try using following procedure :

make partition with fdisk .
make file system with mkfs .
mount your partition with mount .

I get this warning/error "The size of this disk is 3.7 TiB (4000787030016 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). " – Kim André Aug 13 '17 at 20:52
@KimAndré That right. It's exactly as it says. For volumes of 2TB+ the old "msdos" (MBR) partition table cannot be used. – Aug 13 '17 at 21:02
well it seems you using GPT then your fdisk command turns to gdisk . – Ali Ghasempour Aug 13 '17 at 21:02
And howp exactly does this help? My partition is deleted. – Kim André Aug 13 '17 at 21:58
You want to recover your partition ? As your pictures said you have ext3 partition which not shown in your linux ?! so If superblock lost on that partition it's not recoverable . – Ali Ghasempour Aug 14 '17 at 06:21
