Accidently formatted hard disk, then saved some files and again formatted, But now using icare, cant find the previous formatted files.
I don't know what an "icare" is. But to answer your question:
Since we don't do software recommendations, I suggest you have a look on Google or Bing, and find some software that has a good record for data recovery.
Failing that, look at paying someone to recover your data.
It will be very very hard to recover files that have been overwritten, formatting is not that bad, but not overwriting...
Ok, I know what iCare is, but I still recommend "easeUS Data Recovery Wizard". It helped me, BUT I didn't format it 2 times and overwrite it... You can try if you want. For my HDD, it took 3 hours to scan( I know it's long...)
If you're not sure if the software can recover your files, download the free version, it will allow you to just scan(But not recover, unless you but the paid one) And I don't recommend any pirated apps, cause they might contain stuff you wouldn't want.
