How to correct Mistake while partition Recovery

[debanath]

Sir,
1. I have 2 tb WD hard disk,
2. I had three partition including C—windows.i.e 4 partition
3. Earlier it became dynamic disc and the drives were not visible on my computer
4. But 4 partition was visible in Manage section of the computer and other third party recovery software.
5. And while converting dynamic to basic using third party software the partition got deleted and Partitions were not visible any where. The partition did not appear in windows my computer. I could see a single drive which cant be open.
6. My hard disk has become RAW showing in manage section.
7. I ran SMART it shows all correct
8. Then run test disk to recover partition

10. As you did not mention that I have to select the four partition including FAT
D FAT16 <32M 105610 135 54 191475 139 6 1379421430

11. I did not select partitions which we saw after the quick search i.e FAT and execute write .
12. After restart the partition did not appear in my computer it is still RAW
13. Now SMART test successful.
14. I again run test disk
15. Now ---bottom of this screen it says that Hint: EFI GPT was detected. Earlier intel was there

Here is where you check out the readibility of each partition using the "P"-key. If you fail or a missing partitions you should run a deep search and repeat examining the partitions with the "p"-key.

10. As you did not mention that I have to select the four partition including FAT

As this is your first posting, to whom are you refering to when speaking about "did not mention"?

Sir,
kindly refer third link the detailed procedure .

Refer para….
Press
Q
to go back a screen and then press enter to get to this screen.
Select WRITE and press enter in order to write our new partition table to the drive.
DO NOT WRITE A NEW PARTITION TABLE IF YOU DID NOT SEE YOUR FILES/FOLDERS That means the proper partition table was not found and you will have to try a different technique to recover your data.
Where it is not mentined that I have to select all the drive as per last partition
I selected three partition except C drive, Now the hard disk not showing the drives …and search
Shows

You have to use the "p"-key to determine if the partitions found have readible content.
Otherwise continue with deep search and check the content of the partitions.

Set the status of the partitions that contain readible content from "D" to "P" when being in "EFI" or "GPT" mode.
"Selecting" is not enough.
Then let Testdisk write the partition table.
Disconnect, reconnect the drive or reboot if that works.

now ...after deep search

I recovered my data using photorec
but all are scramble.I know the data is there but
Is there any chance to see my older partition ....

You have broken sectors. Search this forum for smartmontools how to get a quick hard drive diagnostic.
Use ddrescue to duplicate the drive.

Use copy/paste or screenshots instead of keying in the output of Testdisk:
