Windows Server 2019 - Disk size not maching the diskpart info
Solution 1:
This has worked for me in the past to reconcile the different sizes for my drives size showing in disk management and windows explorer disk properties:
C\ > DISKPART
DISKPART> List Volume
DISKPART> select volume # (this is the number of the volume listed by the above ‘List Volume’ command)
DISKPART> extend filesystem
DISKPART> exit
