Why Windows Manager is not seeing my disks?

Question

I have 5 that in disk management are shown as initialized, online, basic and unllocated. In Server Manager under "File and Storage Services -> Disks" all of them are visible and in GPT. But in Storage Pools they are no longer visible and can't be added to a new storage pool.

Hello,

The issue you’re experiencing might be due to several reasons. Here are some steps you can try to check the issue:

Check if the disks are set as Read-Only: Open Command Prompt as administrator and type: diskpart. Then type: list disk to display all the disks. Identify your disks by size. For each disk, type: select disk X (where X is the number of the disk), then type: attributes disk to see if the disk is set to Read-Only. If it is, you can clear the Read-Only attribute by typing: attributes disk clear read-only.

Check if the disks have a drive letter assigned: In some cases, the disks might not be visible if they do not have a drive letter assigned. You can check this in Disk Management. If there’s no drive letter, right-click on the disk and choose “Change Drive Letter and Paths”, then “Add” and assign a drive letter.

Check if the disks are Offline: In Disk Management, check if the disks are marked as Offline. If they are, right-click on the disk and choose “Online”.

Check for disk errors: Use the chkdsk command in Command Prompt to check the disks for errors. Type: chkdsk X: /f (where X is the drive letter of the disk) and press Enter.

Update Disk Drivers: In Device Manager, expand the “Disk drives” section, right-click on your disk and choose “Update driver”.

Try a different SATA port or SATA cable: It’s possible that there might be a physical connection issue with the SATA port or cable.
