I have a 1TB internal HDD, that I'm trying to connect externally via SATA/IDE adapter and recover its data. When I connect the drive, it won't show up among other drives.

In GParted (GUI) I see:

  • partition - unallocated
  • file system - unallocated
  • warning - unrecognised disk label

Output of sudo fsdisk -l:

GPT PMBR size mismatch (1953525167 != 244190645) will be corrected by w(rite). Disk /dev/sdc: 931,5 GiB, 1000204886016 bytes, 244190646 sectors Units: sectors of 1 * 4096 = 4096 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0x9a95f0ae

Device Boot Start End Sectors Size Id Type /dev/sdc1
1 1953525167 1953525167 7,3T ee GPT

When I attemped data rescue in GParted, I've got:

The disk scan by gpart did not find any recognizable file systems on this disk.

When trying to mount the drive directly, I get:

$ sudo mount /dev/sdc /media/sebastian/mountpoint
mount: wrong fs type, bad option, bad superblock on /dev/sdc, missing codepage or helper program, or other error

Is there any way I could recover data?

  • Try testdisk for data recovery! – George Udosen Oct 08 '17 at 18:01
  • What does gdisk show? Do not write any data if MBR or post output above so it can be reviewed. https://askubuntu.com/questions/386752/fixing-corrupt-backup-gpt-table/386802#386802 & http://www.rodsbooks.com/gdisk/repairing.html – oldfred Oct 08 '17 at 18:33

    @George It worked, you saved my day, Sir! Thank you. If you would add a solution, I would confirm it.

    Oldfred, Thank you for more information provided.
