"Someone mentioned taking that internal drive out, taking it apart, taking out the disc, and putting that disc in a new internal drive. "
Do not follow stupid ideas, who's said that it must be opened is not relevant to data recovery. It's not hardware problem, totally pointless to dismantle the disk. Anyways, without a HEPA14 filtered clean room is more pointless.
Take the drive out, connect on SATA directly to the motherboard and use DMDE free version! The free version allow you up to 4000 files from one directory to be recovered. That limitation is per run, so you can always just exit it and then open again to recover more from either a different directory or another 4000 from the same.
If the only logical damage involves the partition metadata (ie. sectors 0,1,2), then DMDE should be able to restore this information. Can you show us the partitions window in DMDE?
Do not touch anything beyond that!
