Hello digger:
first off there is nothing in the bios that is going to assist you in regaining your files. If you are just plain interested in learning the bios you can find that info in our "Tips & Tricks" section. I will warn you; please dont mess with any bios setting until this matter has been resolved, dont want the water getting any muddier.
Second suggestion; I would purchase the program "Getdataback" recovery program, they have a trial version which scans your drive and then you can see if this recovery program will work for you before you pay! This prog is a tad pricey at $89.00 I think, but you must assign your data a value ?
here is the link to that prog:

third comment: the PC to PC networking cable will not help you until your computer can access or "see" the data. I would pass on that endeavor.
Once you have recovered your drives data then you can reformat the drive and live happily ever after; :wave:
