This is continuation of Recover Extended Partition , but this time I have different problem related partition table it self.

I managed to restore partition that I needed and backed up files that were crucial to me (at least those that I had space to store somewhere)

OK now get to the problem. My partition table is corrupted, booting RIP Linux I can mount it in truecrypt (and other ones that recovered), but that's basically it. When I launch GParted I have unallocated drive.

GParted Dev info:

Device Information

Model: ATA ST2000DL003-9VT1
Size: 1.82TiB
Path: /dev/sda

Partition table: unrecognized
Heads: 255
Sectors/track: 63
Cylinders: 243201
Total Sectors: 3907029168
Sector size: 512

When I check information on unallocated space I get:

File system: unallocated
Size: 1.82TiB
First sector: 0
Last sector: 3907029167
Total sectors: 3907029168

Warning: Can't have a partition outside the disk!

Now the output of testdisc (Analyze):

TestDisk 6.13, Data Recovery Utility, November 2011

Disk /dev/sda - 2000 GB / 1863 GiB - CHS 243201 255 63
Current partition structure:

Now fdisk:

# fdisk -l /dev/sda

Disk /dev/sda: 2000.4 GB, 2000398934016 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda6       328212480  3907028991  1789408256    7  HPFS/NTFS/exFAT

Now I would like to fix that to arrange partitions correctly, but I have no idea which tool is capable of fixing that (tried, a few, some of them offered fixing, but it was to risky at the moment - still backing up data).
