Hello Folks

So yesterday my Seagate 1tb drive of a year old suddenly disappeared from my windows when I was copying content onto it.

It appears in bios as my D drive, and when i open up disk management, it says there is 100% free space and it's in RAW format. Rescaning disks and refreshing does not help.

I know for a fact that there was at least 800gb worth of files onto it.
What else can I do to make windows recognise the drive and get my files back?
