Use Device Manager to scan your computer's hardware for changes. Then, use the DiskPart rescan command if your disk configuration has changed but the changes do not appear in Disk Management. For more information about Device Manager, see Related Topics.

When DiskPart rescans disks, it scans all attached disks for disk configuration changes. It also updates information on removable media, CD-ROM drives, basic volumes, file systems, and drive letters.

Rescanning disks can take several minutes, depending on the number of hardware devices installed.
