Many lower quality data recovery programs rely on a very simple system to find and recover lost files. All these programs are capable of doing is searching through the boot sectors of your computer’s hard drive and looking for listed within its programming script specific file extensions. These popular file extensions such as DOC and JPG files are used commonly and all that is required to locate them is a basic search function much like you would use in Microsoft Word to locate a phrase.
And very often the boot sectors themselves have been damaged on your computer’s hard drive and are no longer able to offer a listing of the hard drive sectors contents. When this happens a data recovery program must be able to recognize file construction data so as to be able to sort and reconstruct files. When attempting to recover Outlook Express files on computers with bad boot sectors it is imperative that you use a quality program designed to recover DBX file types by recognizing the inner coding.
