<\/p>\nWhen you open Disk Management, the volume size (i.e., capacity) may be misreported in the top pane. The bottom pane, which shows the graphical view, may report the capacity correctly for each volume.<\/p>\n
<\/p>\n
Although the exact cause is not known, you can fix the issue using Diskpart.<\/p>\n
Note: Before using Diskpart or any other disk management tool, it is recommended to back up the data from the specific partition to an external drive, just in case.<\/em><\/p>\n Run the following commands from an administrator command prompt:<\/p>\n Note:<\/strong><\/p>\n In the list volume<\/strong> output, note the volume number or the drive letter of the volume that is facing the issue.
