The FBI has the original Hard drive. Could a prosecutor get it from the FBI?
Still a chain of custody problem. The FBI didn't get the drive from Hunter Biden. They got it from a Trump-supporting shop owner who called them but who can't swear who brought it in, and who had it in his sole possession with full access for several months at least. Add to that fact that it's been used for partisan political purposes, which will be used to attack it's veracity. And any investigation that proceeds from it might be considered "Fruit of the Poison Tree," as they say.
