What is the result if you run "cmd" (right click "run as administrator") and "chkdsk /f e:" ?
If it doesn't work, it's always possible to use PhotoRec but it will not recover the original filenames of your lost files.

i can recover some of it ( the first one partition data ) but i need the other one in there folder is that possible ?

or how to fix this partition with the data that it showed me in minitool ( minaaaaaaa) folder and i can forget about the other one data

MFT and its mirror are perfectly matched win i finished the rebuilding boot sector

The boot sector is damaged. Can you try TestDisk, Advanced, Boot, List ?
If it works, choose BackupBS and confirm.
If it doesn't, try RebuildBS, List, choos Write and confirm if you can see your files.

RebuildBS when i did it before it erased the data in the second partiton i don't want take any risk
for my other data

1-TestDisk, Advanced
2-boot is bad
3- List i have my files already in my drive minaaaaaa folder
4- BackupBS not shown to me before i did RebuildBS
