For anyone who has a need to recover data software is the most difficult part of the process to find. There are thousands of data recovery programs available but only a handful are effective. You can of course sift through hundreds of data recovery programs testing them one at a time but a few guidelines will make finding the best data recovery tool a simple procedure.
To begin let us look at what your exact requirements are. If all you need data recovery software for is to rescue a few files that you accidentally deleted then the ability of a data recovery program to work quickly is not too much of a factor. For your use you will want to find a program that has an excellent preview system. This will allow you to find exactly the program you lost. This especially applies to data recovery software aimed at photo recovery. Usually in this instance you will be searching through a smaller media storage device such as a camera smart card or iPod drive. These can be scanned very quickly but you will want to be able to rapidly choose which photos or songs to save.
