When Storage Foundation for Windows rescans disks, it scans all disks for disk configuration changes. It also updates information about CD-ROM drives and other removable media, basic volumes, file systems, and drive letters.
Rescanning disks can take several minutes, depending on the number of hardware devices installed.
Note the following:
You should rescan disks when you remove disks from or add disks to a computer.
From the Actions menu, select Rescan.
If you click the Tasks tab at the lower left corner of the VEA window, information on the progress of the rescan is displayed in the window's lower pane.
More information is available.
