Summary

A newly installed SSD may appear in the system BIOS and Windows Device Manager but not in Disk Management. In many cases, Windows Storage Spaces has automatically added the drive to an existing storage pool, preventing it from appearing as an available disk in Disk Management. Removing the SSD from the storage pool can resolve the issue.

NOTE: This solution depends on you having Windows 11 or Windows 10 installed on your computer. Storage Spaces must have been set up prior to you installing your new SSD. If you do not have storage spaces configured on your computer, this guide is not going to help you. See the Dell Fix Hard Drive and SSD Issues library page for further help with storage drives.

Symptoms

After installing a new SSD:

  • The SSD is detected in the BIOS.
  • The SSD appears in Windows Device Manager.
  • The SSD does not appear in Disk Management.
  • The SSD cannot be initialized, partitioned, or formatted through Disk Management.

Cause

If Storage Spaces is configured on the computer, Windows may automatically add the new SSD to an existing storage pool. When this occurs, the drive is not presented as a standalone disk in Disk Management.

Resolution

Prevent the Computer from Sleeping During Drive Removal

  • In Windows 11: Type Power and battery in the Start Menu, and then select screen and sleep. Change When plugged in, put my device to sleep after, to Never

  • In Windows 10: Type Power & sleep in the Start Menu, and then select power and sleep settings. Change when plugged in, computer goes to sleep after, to Never

Remove the SSD from the Storage Pool

  1. Open the Start menu.
  2. Search for Storage Spaces and open it.
  3. Select Change settings.
  4. Select Physical drives to view all drives in the storage pool.
  5. Locate the newly installed SSD.
  6. Select Prepare for removal.
  7. Keep the computer powered on until the drive status changes to Ready to remove.
  8. Select Remove > Remove drive.

Verify the Resolution

After removing the SSD from the storage pool:

  1. Open Disk Management.
  2. Confirm that the SSD is now visible.
  3. If prompted, initialize the disk.
  4. Create and format a new partition as needed.

Additional Notes

  • This resolution applies only when Storage Spaces is configured on the system before the SSD was installed.
  • If Storage Spaces is not configured, see the Dell Data Storage, Backup and Recovery library page for further help with storage drives.
  • If there is insufficient free capacity in the storage pool, Windows may not be able to prepare the drive for removal until data is redistributed to other drives in the pool.

FAQ

Why does the SSD appear in BIOS but not in Disk Management?

The SSD is being detected by the hardware and operating system, but Storage Spaces may have claimed the drive as part of a storage pool, preventing it from appearing as an independent disk.

Does this issue indicate a faulty SSD?

No. If the drive is visible in BIOS and Device Manager, the SSD is often functioning correctly. The issue may be related to Storage Spaces configuration.

Is this applicable to both Windows 10 and Windows 11?

Yes. The documented resolution applies to both Windows 10 and Windows 11 systems using Storage Spaces.
