I'm working on a computer and it is having an issue I've never really seen before.
The computer has two physical drives, both 500GB. Drive 0 is C: with the operating system, system reserved, and recovery partition.
Drive 1 is D: with the whole drive as 1 partition.
Windows (both in explorer and disk management) reports that drive D: has only 66 GB of free space left.
However, other methods report that the drive has only 34 gigs used, so approx 432 GB left.
These methods include just selecting all files and directories visible in the drive and checking properties, and running WinDirStat on the drive. If I check the option "Show Unknown" in windir stat there is a giant file (or block of space) that windirstat estimates around 300 gb
I even changed it to show hidden files and folders as well as show protected operating system files but all the did was reveal the "$RECYCLE.BIN" folder which Windows reports to be 4KB.
I have tried researching this online but so far haven't found anything that really helps.
Does anyone here have any idea as to what might be happening?
