I want to test the Testdisk Tool as many of my friends said using it they managed to recover their hard disks by 100%, 90%, or 80% or so. My data inside were Kubuntu operating system and thousands of files (yes, I installed OS not within HDD but simply USB flash drive). I deliberately sacrificed my 'hard disk' (a 32GB EXT2 USB flash disk drive actually) by doing resizing and experienced fatal failure.

Suffice to say am very afraid to write only one partition to the device with the knowledge that it actually has two.Subscribe to UbuntuBuzz Telegram Channel to get article updates. When I select one as primary boot I get this on the next screen Disk /dev/sdf - 15 GB / 14 GiB - CHS 15072 64 32 Use Up/Down Arrow keys to select partition. P Linux Swap 121535 178 52 121600 215 7 1046512īut if I try to set this on the corrupted disk I get an error: Disk /dev/sdf - 15 GB / 14 GiB - CHS 15072 64 32 On another (Debian) system I have this structure: Disk /dev/sda - 1000 GB / 931 GiB - CHS 121602 255 63 If I select 0 as primary bootable (I think it is the /boot partition) I cannot make any valid selection for 1 (It does not allow me to chose either Logical or Extended) However I cannot seem to recover both partitions. Partition 1 is also correctly seen as: ext4 blocksize=4096 Large file Sparse superblock Backup superblock, 15 GB / 14 G Keys A: add partition, L: load backup, T: change type, P: list files,Įxt2 blocksize=1024 Sparse superblock Backup superblock, 254 MB / 243 MiB *=Primary bootable P=Primary L=Logical E=Extended D=Deleted

Use Left/Right Arrow keys to CHANGE partition characteristics:

However when I run quick scan it clearly sees my partitions: Disk /dev/sdf - 15 GB / 14 GiB - CHS 15072 64 32

Now I run testdisk and I get this in the first analyze step: Partition sector doesn't have the endmark 0xAA55 My NAS got a corrupted partition table yesterday (I don't know the cause)

Testdisk recover partition
