Windows Server free hdd space and capacity mismatch

Terry_CWQ 1 Reputation point

Hi, I noticed a strange behavior with one of my windows server lately, the hard disk space automatically increases by itself every few mins till max capacity and then automatically decrease itself again to free up space. Not sure what's going on here and i can sometimes see e.g free space is 203GB when the given HDD capacity is only 130GB. It shows the same in disk management as well.75769-disk1.png

    Sounds like misbehaving or driver compatibility issues. The server manufacturer will be your best resource here to trouble shoot.

    1. Please try to open CMD as administrator, then run sfc /scannow to check if there's any error.
    2. Please run anti-virus scan to check if there's any virus in the system.
    3. Besides, it's recommended to backup the server, and then try to run chkdsk /f /r on the drive to see if there's any error.

    Thanks for your time!
    Best Regards,
