To check the health of your hard disk in Windows Server, you can use the built-in tool called "Disk Management". Here are the steps:
Open the "Disk Management" tool by typing "diskmgmt.msc" in the Run dialog box (press Windows key + R to open the Run dialog box).
In the Disk Management window, locate the disk you want to check. You can identify the disk by its size and drive letter.
Right-click on the disk and select "Properties".
In the Properties window, go to the "Tools" tab.
Under the "Error checking" section, click on the "Check" button.
Windows will now check the disk for errors and report any issues it finds.
