In data recovery, you get what you pay for

A final factor in choosing the best data recovery program is price. Don’t be misled by programs promising to do it all for just $34.95. These are always obsolete programs that can only accomplish a simple fast scan for recently deleted files. Look to spend from $129.00 to $449.00 for a quality data recovery program that can completely scan a large drive in around three hours and will return around 95% of all files even from a reformatted drive.
