When choosing a program for crashed hard drive recovery begin by recognizing which operating system type your computer uses. For the most part this is extremely simple, there are only three. Those are Microsoft Windows, Mac OS X, and Linux. While all of these have variations and versions the fundamentals inherent in each remain the same, as such hard disk data recovery software for the given operating system should work on every version offered by that application.
Remember the limitation on this is that hard disk data recovery software for these different operating systems is not interchangeable. You will not be able to use a Windows data recovery program to recover files on your Apple Macintosh. Likewise you will not be of use a Windows recovery system on a netbook running Linux Ubuntu. Once you choose the data recovery software which corresponds to your computer’s operating system it is a fairly simple matter then to direct that program to scan through your computer’s hard disk drive and create a list of recoverable files. Most of these programs will recover a single accidentally deleted file or if need be every file on an entire hard drive.
