Is it possible to recover date from a pen drive from which the file system itself has been corrupted and the system is asking for formatting it even having data in it?

Are there any free (freeware) Data Recovery Software? If yes, which is the best?

If the file system is corrupt, you are most likely out of luck.

Here is a link to a freebie that might help:
PC Inspector

Best of luck,

Hi,
I do not often promote my own sites, but in this case I recently added the reconstruted page to this site. It has a "Freeware" section for Windows in the right-hand column if you scroll down. Types of programs are categorized.

Here is a trusted site that reviews freeware. I've linked you in directly to the file recovery utilities: Best Free Data Recovery / File Un-delete Utility
