Mini tool worked got my data back!

Thanks Everyone,
Roger

OK, I'll try Mini Tool Free. If it works I'll pay the $69 Bucks. Very much like ransom ware isn't it! That is about my limit though not worth the forensic data recovery.
Then I will just reformat...

I had 500GB of data on the drive! Is there a way to recover it? - or - Did I lose it all when I Foolishly chose GPT?

Thanks for the replays,
Roger

When I tried to access the disk it gave me 2 choices. The first one did not work because of an error I did not recognize. Only choice left was GPT. I wish I would not have clicked that one! Any help...
