I've recently set up a new W11 machine with a clean install and a couple of games, and the system had a random BSOD. The strange part though was that after recovering the system did a disk scan and repair, and on boot up afterwards most of the games plus Steam itself had disappeared from the system.

After reinstalling the games the system is now consuming nearly twice as much space on the SSD as it was before. Windows Explorer reports that 474GB of space is being used, but there's only 243GB of data in the drive if I select every folder inside it and check properties (including hidden files). There's only 2 newish AAA games each with somewhere between 50 and 100GB each, and some smaller/older titles; notably the amount of data that went missing after the crash is probably close to 200GB, so I suspect that the missing data is still floating around, but because it's not visible anywhere it's just taking up space.

Is there any way to delete this orphaned data? I've tried Disk Clean-up but it could only find less than 100Mb of temp files and what have you.

You may have a corrupted filesystem, since it died in the middle of writing. Run chkdsk

chkdsk c: /F /X

This fixes errors on disk (F) and forces volume to dismount first if necessary (X). or

chkdsk c: /scan /forceofflinefix

If it finds any errors they are fixed at next reboot.
