Re: How to recover lost data
The same company that sells GetDataBack sells RecoverMyFiles -- and like the former, you can download a trial version, install it to a Windows PC, connect your drive, run it against that drive -- and see what it finds.
IF it finds your files, you will have to go online to purchase a license to do the actual recovery.
Last time I checked, the license was around $80 USD.
Ubuntu 12.10; Mint 15; MS Win7 & Win8.
Will not respond to PM requests for support -- use the forums.
