This shows that the drive's condition is deteriorating, since the drive would have been recognised by the BIOS for typical "user" recovery software to work. Now, as you've explained, the drive is no longer recognised by the BIOS

As

You won't have the necessary tools, equipment & experience to have a realistic chance of success doing mechanical work.
Using the services of an experienced DR company seems like your best choice, if the data is valuable.
