How do I recover accidentally deleted partition & its data?

The event has passed. Only cremation remains. :)

You may post the following information "I was using disk management tool on windows 10 to delete the volume E" Where is E? I don't see it.

You deleted D. What was its extent in GB? Is it the current D 44.36GB + unallocated 80.94 GB = 125GB?

You created a new volume D. Did you format it too? ( Looks like you formatted and it was not just the creation of new volume)

Also run Getdataback simple and see whether you can see any files in the various partitions in it. ( It only scans and does not write anything to the drive. So absolutely safe.)

Off now.

Returned to station just a few hours ago. Whenever you want to continue , you may do so.

Thank you so much Jumanji for getting back on this. I hope everything was all right on your trip.

I have changed the letter of drive E to U.
No the size of the D drive was 42 GB.
Yes I formatted it.
I did run Getdataback but unfortunately I do not see any of my previous files.

I hope I answered all your questions. I feel that I lost my data & there is no way to get it back since I formatted it and created new one out of the unallocated space ? Is that true ?

If you had formatted D, the original MFT ( Master File Table) is gone. You may try PhotoRec to rebuild whatever data is there. You won't be able to get the original folder structure and File Names. What you will get is only a bunch of files without the original file names. You have to rename those and reorganise into folders.
