Cannot recover WD 3TB partition.

#1 Post by radagast » 23 Sep 2017, 22:00

Hi all,
I was trying to recover the partition of my external 3TB HDD by using testdisk. Unfortunately it was unsuccessful. I followed the procedure but it shows the same problem again.

Here is my setup:
1. Linux Mint 18.2
2. HDD connected through USB
3. HDD size: 3 TB, 1 NTFS partition

I am posting my screenshots here,

I have restarted the PC and it seems it didn't work.

My log file looks life this,

Hint for advanced users. dmsetup may be used if you prefer to avoid to rewrite the partition table for the moment:
echo "0 5860464640 linear /dev/sdb 2048" | dmsetup create test0

interface_write()
 1 * HPFS - NTFS              0   4  5 45599 165  6  732558080 [3tb]
write!

write_mbr_i386: starting...
write_all_log_i386: starting...
No extended partition
You will have to reboot for the change to take effect.

TestDisk exited normally.
Anyone have any idea what am I missing here?

Run TestDisk, ANalyse, Quick Search, use 'a' to manually add the partition
HPFS - NTFS 0 32 33 267349 121 35
Set this partition as *(bootable), the other (if any) as D(eleted).
On next screen, choose Write and confirm.

Now, choose Advanced, you must have
1 * HPFS - NTFS 0 32 33 267349 121 35 4294967295
Choose Boot, RebuildBS, List. If you can see your files, choose Write, confirm, Quit
Restart your computer.

Thanks for the reply. I followed the procedure you have suggested and come up with this after clicking rebuild,

The partition listed in your screenshot doesn't match the partition I told you to recover...
