Not recognized drive.

My pastor had a hard drive crash last year He had a new drive installed, but the repair shop said they could not get any data off the crashed drive. I took the drive to another shop were the drive was plugged in via a USB cable. The drive could not be recognized and I was told there are no options. Many family and church pictures on the drive (of course noone did a backup of any kind). Shop pulled the board from the drive and saw no obvious damge. Can we get another drive and swap the platters in hopes the platters are okay? I understand dust free space is very important. Any thoughts?
Thanks!
