I keep/kept all my website creation files on my 2TB internal drive which was my D drive. Just over a week ago a friend asked me if I could update her site. When I went to the D drive it had changed letters and became X drive and all my other internal drives except C (O/S drive) had changed letters too. Not a biggy this as I could have remapped them but, the contents of the D (now X) had been overwritten by the contents of the C drive???
I had backed-up the D drive to my external 4TB hard drive but that too had been overwritten too by the contents of the C drive and the backup file had disappeared?
I have ran several scans to see if a virus had got through but nothing has shown up. I have ran several demo data recovery programs through the drive but none of the folder/file structure has shown up.
I have never heard or come across anything like this before! Not sure if you have any ideas on this or can help?
I do have screenshots of what the file structure looked like before the issue if that would help?
I have once used Easus Partition recovery manager when a similar thing happened on a grand daughter's laptop where somehow the recovery partition filled up to overflow and she lost stuff. Have a read - it is Free
If not too much activity has occurred on your D/X drive since it corrupted then Recuva from Auslogics might enable you to get back all the missing files and transfer them to another folder. Good luck with it.
