PW Quick scan tries ty find a partition. It starts from beginning of disk. If PW finds one.... PW knows the size and proceeds with searching and the end of already found partitions.

Are you 100% sure you did "quick scan"? Are you sure you did "clean" and not "clean all"? Other recovery tools didn't find the partition as well. So there's really nothing written to that disk after the "clean" command?

Yes i did a quick scan only. And I did clean only as I was not aware of the clean all command at that time. So there's no way i could have run the clean all command and yes I did absolutely nothing to the disk after I did that as I knew that would completely destroy my data

As of now i am back to MiniTool Partition Wizard and I am running quick scan. This is the screen so far

What happens is impossible. At least if you only did "clean", it was a MBR disk and the documentation is correct and you didn't write to the unallocated space afterwards.

PW quick scan should fix it.... at least normally.
you can try deep scan but that takes maybe days.

testdisk is very good tool for this and is use for forensic analysis as well. If "deeper search" doesn't work.... I am out of options to recover the partition.

But I think I CAN rescue the files!! What type of files are on that disk?

It was MBR disk for sure. And also i ran only clean command but I guess i am out of those 1% who are out of luck I am running Minitool Partition Wizards Quick scan now which is taking ages but ill put the screen here when done. If it doesn't fix ill run TestDisk Deep Scan once more before I give up.

There were a lot of files of various formats like videos, photographs, archives(zip, rar), executables(program setups), and iso's.

Out of which the iso's are most important to me. But still its like 2 to 3 years of data I am not sure what exactly I lost. But a lot of "user data" that accumulates in one's pc you can say.

Do all the things I advised you to do. And post results.
No partition recovered at all.... it's time to try to recover a lot of files.

Please read PhotoRec - CGSecurity
Did you defrag the disk drive recently, so files are (almost) contiguous? This helps PhotoRec

Deep Scan Results - Testdisk

These are the results of my deep scan from Testdisk

Doesn't look like it recovered anything. I'd run a full scan by Partition Wizard now and see if it finds anything then i'd fall back to file recovery

Download and install sector inspector as explained on Tools for MBR/Boot Records and References

Open an Elevated Command Prompt
then do
Code:
c:\path\to\secinspect -backup PhysicalDrive0 mbrsect.txt 0 2048
replace path\to with the real path. Replace PhysicalDrive0 with PhysicalDrive1 I assume. See disk management for actual drive number. mbrsect.txt will be created in the current folder and has the first 2048 sectors. File size is 1MB. Please post the file as attachment.
