As far as my experience goes there isnt much software alone can do if the drive is not recognised by the bios. There may be a problem with a crashed head that impacted a plater. File recovery professionals can remove the platters and place them into another hard drive to try and recover the lost files. This has to be done in a clean room. If any dust gets on the platters the platters can be permanantly dammaged.
