Recovering NTFS Partition from (partly?) quick-formatted drive

#1 Post by shiz0 » 17 Sep 2016, 08:31

Hi.
I dont know if this should be in here, or in FS recovery. Apologies if so:

I have here a 1TB disk a friend gave to me. It was his data drive.
He accidentally quick-formatted the wrong disk. :roll:
As soon as he got aware of his error he killed the pc. :roll:

Now the disk is detected as follows:

Code: Select all

# lsblk -o NAME,FSTYPE,SIZE,MODEL
NAME   FSTYPE            SIZE MODEL
[...]
sdi                    931.5G Hitachi HDS72101
└─sdi1                 931.5G

Code: Select all

# fdisk -l /dev/sdi
Disk /dev/sdi: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x7f99d2ff

Device     Boot Start        End    Sectors   Size Id Type
/dev/sdi1        2048 1953521663 1953519616 931.5G  7 HPFS/NTFS/exFAT
In Testdisk, the Drive and also the Partition seems to be detected okay:

Code: Select all

Disk /dev/sdi - 1000 GB / 931 GiB - Hitachi HDS721010CLA332

Please select the partition table type, press Enter when done.
>[Intel  ] Intel/PC partition
 [EFI GPT] EFI GPT partition map (Mac i386, some x86_64...)
 [Humax  ] Humax partition table
 [Mac    ] Apple partition map
 [None   ] Non partitioned media
 [Sun    ] Sun Solaris partition
 [XBox   ] XBox partition
 [Return ] Return to disk selection

Hint: Intel partition table type has been detected.
Note: Do NOT select 'None' for media with only a single partition. It's very
rare for a disk to be 'Non-partitioned'.

Code: Select all

Disk /dev/sdi - 1000 GB / 931 GiB - Hitachi HDS721010CLA332
     CHS 121601 255 63 - sector size=512

In "Advanced":

Code: Select all

     Partition                  Start        End    Size in sectors
> 1 P HPFS - NTFS              0  32 33 121601  25 24 1953519616
Trying to list the files fails with error "Filesystem seems damaged".
So first, I go with quick search, and the deeper search, but it only detects some FAT32 Partition with wrong size and says the disk is too small.
The I can only go back to the menu. Going for "Advanced" in Boot Repair it says both boot sectors are bad. Trying to rebuild them fails.
Am I missing something?
I just started the process over from the beginning to get a clean log file.
I will append it here, as soon as its finished (will take some hours ofc).

Any help appreciated.
Thank you.

In Advanced, try Boot, RebuildBS, List. If you can see your files, choose Write, confirm, Quit and restart your computer.
If it doesn't please post the testdisk.log file content.

During Scans (normal, as well as deep) it outputs:

Code: Select all

Invalid FAT boot sector
 0 D FAT32 LBA            36883 158 33 279707 107 49 3900964364
  FAT32 LBA            36883 158 33 279707 107 49 3900964364
Normal scan finished:

Code: Select all

Disk /dev/sdi - 1000 GB / 931 GiB - CHS 121601 255 63

The harddisk (1000 GB / 931 GiB) seems too small! (< 2300 GB / 2142 GiB)
Check the harddisk size: HD jumpers settings, BIOS detection...

The following partition can't be recovered:
     Partition               Start        End    Size in sectors
>  FAT32 LBA            36883 158 33 279707 107 49 3900964364


[ Continue ]
1997 GB / 1860 GiB

I will try rebuilding the BS right after the currently running deep scan is finished.
That again will take some hours scanning all the sectors :arrow:
I will report back to you and post the log file after it's all done.
Thank you!

Unfortunately, after trying to rebuild BS, they are still listed as bad.
Listing files is still not possible:
"Can't open filesystem. Filesystem seems damaged."

In the log there are MFTs found, but "read_mft_info failed".
Here's the log:

Code: Select all

$ cat testdisk.log
