Depends on on much you want to spend.

If the drive motor and controller is good then it's a good possibility (bad sectors on the platter creating the non-boot condition).

If either the motor or the controller is toast then it gets quite a bit more expensive. You send it to a place which has a "clean" room, they pull apart the old drive, re-install a motor and controller and burn the info to either a new drive or DVD.

I used to use a place in New Hampshire for my clients' EXTREMELY important documents (lawyers, accountants, etc.) for data recovery. It wasn't cheap back then (mid '90's), about $125 an hour, minimum 2 hours with NO guarantee. You paid shipping and insurance both ways. There are probably more places around. Do a "data recovery services" search on the web.
