As it says in the title. Installed 2TB Nvme a couple of months ago, and migrated Windows from a standard, sata ssd using the Data Migration tool. Migration added an extra small drive/partition (F:System) of around 1GB.

Suddenly, today, it's only showing in Windows Explorer as 1TB, and a huge chunk of data has disappeared, mostly games, and the F Drive has gone completely .

The Evo is showing in Samsung Magician as the full size, but Windows Disk Management is now showing the old C drive as the boot drive. Samsung's Disk Migration tool is showing the Evo as the target drive, but won't allow me to select the C: as the source drive. System Recovery is of no help whatsoever, as it appears to have switched itself off for all but the E;(Evo) drive and there are no restore points other than the one today when I re-installed Data Migration

Any and all suggestions and help in recovering would be very gratefully received
 
I think I've spotted the problem... but don't know how to proceed.

It appears that the drive letters have been switched. I've just noticed that the old C: drive, a 1TB sata ssd, has been changed to the E: drive, and the new EVO changed to C:

For the moment, I've just changed the shortcut icons of the missing games target to the C: drive... and I'm good to go
Thanks for concentrating my mind. Still puzzled as to why the system changed the drive designations without asking

The drive or partition the system boots from WILL be the C drive.

Before deleting anything, test.

Power off.
Physically disconnect ALL other drives.
Power up with ONLY this new drive connected.

This should have been done as the first step after the migration process.
can't atm, but will deal with it tomorrow. Again, thanks for the help... and consider me suitably chastened :blush:
