I am using Windows 7 currently, and my main hard drive is a Western Digital 1TB Caviar Black along with a secondary Caviar Blue drive. My kids deleted some of my files/folders on accident and got a virus, so I had to reinstall Windows 7 on one of the two drives. I really need those files back.when I search I can see the specific folders, but the files are missing. I'm talking about work related files, years of family photos and my entire ITunes library of almost 18,000 songs. What software can I use for internal drive data recovery since Western Digital doesn't offer any from their site? Also, can I use another brands software, like Seagate for example or 3rd party software. Please Please help!
