What Is an Offline Disk
Disk Management displays the Offline status when a dynamie disk is not
accessible. The inaccessible disk may be corrupted or intermittently
unavailabie. The Offline status also appears if you attempt to import a foreign
dynamie disk, but the operation fails. An error ieon appears on the offline disk.
The Offline status appears only for dynamie disks.
When you remove a dynamie disk from a Computer, the remaining online
dynamie disks retain information about it and its volumes. Disk Management
displays the removed disk as a Dynamic/Offlinę disk named Missing. You can
remove this Missing disk entry by removing all volumes on that disk and then
using the Remove Diskcommand that is associated with that disk. When you
physically remove the last dynamie disk, the Missing entry is no longer
displayed in Disk Management.
Reactivating or rescanning an offline disk changes the disk status from Offline to OK.
