It is possible to recover in some cases, but there is a chance the files were overwritten as some others have said. If these files are very important, immediately stop using the drive to prevent further damage. If you have the budget, hire a professional data recovery company to attempt a recovery.

I formatted and made 2 partition C, D.

Any way to recover that small folder that was on the HDD?
