I don't have a solution. But a warning. The more you do to fix the problem, the worse it will become.
You need to find a wanton make a forensic copy of h your hard drive. Wait, better let someone else do that.
If thins is really important to you, you may have to employ a
data recovery service to find files that were marked for erasure.
What they change is hard to say. Ask among your contacts for a service that know of in your area. Otherwise, you need to contact a expert service and ship the drive per their instructions.
Start with Seagate. They offer data recovery. For a price. Or choose another if you are confident they are reliable. You may nobly get one shot a t getting back your data.
