I am not being unkind but as you have proceeded to full format the hard drive and may have problems restoring the data, you might want to see if there is any Amiga users in your area with some more expertise who can go on-site and resolve the problem.
As the data is obviously important, making any more mistakes could make it harder still for someone knowledgeable with Amigas to help you.
Its up to you. I am a computer technician myself, but beyond my remit I regularly employ experts in other areas of IT to carry out tasks.
