It would be really appreciated if someone could teach me how to recover/fix damaged data from a SSD.
The wife uses a Samsung 850EVO 500G SSD with a SATA to USB 3.0 cable as a daily working drive. Last week, she used FreeFileSync to backup her data to a Seagate hard drive, which is her backup drive. We do not know what happened, but FreeFileSync deleted all her new data on Samsung SSD and replaced them with the old data from the Seagate drive. The wife only backs up data twice a year(not wise and stubborn), so she lost half year hard work. Most of them are SAS code/data and Excel files.
I tried to recovered these deleted data from the SSD and looks I got almost all the data back. However, only like 5% of them could be opened, although all of them show the real size. I tried different software, including R-Studio/DMDE/EasyRecovery/Getdataback, but all of them have the same results.
I do not know how FreeFileSync worked and what caused the recovered data damaged. I had recovered deleted data from HDDs several times before, and every time it was easy and successful. I check the SSD that the TRIM support is enabled. Maybe that is the reason why I cannot get the data back.
All these happened on Win7 system and half of the SSD was empty.
Please help us! Thank you in advance!
