Data Recovery after using diskpart clean command

OK fine you are at GMT+3 and I am at GMT+5:30. Please change your time zone in USER CP. Settings &options>Edit Options> Date and Time options. Change Time Zone to GMT+3. That should show your correct Local Time in your post ( and I need not deduct 2:30 from my local time to get your local time. I am weak in mathematics )

Your TestDisk screenshots appear to be OK but I shall rework it and present it when I get back. ( I have an appointment with the optholmologist for my wife and running away now)

OK, the worksheet for you is ready. I still can't say what will be the final result. Our friend Bongolia in this thread Flash files restored but with generic names. Partition notfound. was able to get all the files using PhotoRec ( but without the folder structure and original file names) but was able to get the folder structure and original filenames using the free demo version of GetDataback simple. In your case using GetDataback simple is out of consideration since you have formatted D:.If data is still there PhotoRec will definitely reconstruct the files. Let us see your luck.

Run PhotoRec with your destination external drive plugged in.

Screen 1:



Highlight/Select your formatted drive. Note the drive letter of your destination external drive.( In your case it may be different) [Proceed] is highlighted. Press Enter key

Screen 2:



Your drive D: partition P NTFS is highlighted. Move the highlight from [Search] to [File Opt]. Enter

Screen 3:



Toggle s to select/deselect all file types. If you know what file types you want to copy, you can deselect all types and select/highlight only those file types by putting X in [ ]. PhotoRec Scan will take less time. If you don't mind a long run, then select all file types. 300 GB will take quite a few hours.

Press b to save the selection. Do not forget

Screen 4:



Settings Saved. Press Enter.

Screen 5:



[Quit] is highlighted. Press Enter to return to the main menu.

Screen 6:



Back to the main menu with Drive D: Partiton P NTFS highlighted.

Move highlight from [File Opt] to [Search] Press Enter.

Screen 7:



Highlight [Other] Press Enter.

Screen 8:



Highlight [Whole] Press Enter

Screen 9:



Select Destination: Default shown Directory ; \testdisk7-0. No No No We want Directory I: /Recovery

Press Left arrow key to go one level higher. EDITED: It is not the right arrow key but left arrow key

Screen 10:



You are at Directory C: \ Still a No No

Press Left arrow key once again EDITED : Again Left arrow key

So you will press the left arrow key twice.

Screen 11:



Voila! you see all the directories (drives) . Move the highlight to the drive letter of your external drive - which you noted in screen one.

Press Enter.

Screen 12:



You are still in Directory I: \ that is the root. You got it. You can see all the folders on your external drive. Move the highlight to the Recovery Folder and press Enter

Screen 13:
