What do you mean by "they were not so efficient!"?
These data recovery programs could not work or didn't restore your wanted files back completely?
In my experiences, there are indeed some data recovery freeware on the internet, which could even work better than some paid ones, such as Recuva, iCare Data recovery Free and TestDisk, etc. Have you tried them all?
If these free ones really make no sense, you may ask for a professional service, though that may cost a lot.
Hope this works for you!
Hello! This is my issue:
I accidentally deleted some documents on my laptop and these were needed for school. I'd been searched for several days on how to recover them back from my PC. I had tried some free data recovery programs. But, they were not so efficient! Does anyone know such as free program? Any idea could be appreciated!
