Burnt SATA Drive

"Theoretically you may be able to replace the PCB with one from an identical drive. Note that manufacturers sometimes use slightly different boards even in the same model series, so you would really need an identical one.

It's possible but somewhat unlikely that the platters (the actual hard drive) is damaged but even if you succeed I would only do that to read data off the drive and then replace it.

And yes, it is also possible that it's damaged beyond repair."
