In storage area network (SAN) configurations, disabling automount prevents Windows from automatically mounting or assigning drive letters to any new basic volumes that are visible to the system.


automount [ { enable | disable | scrub } ] [noerr]


Parameter Description
enable Enables Windows to automatically mount new basic and dynamic volumes that are added to the system and to assign them drive letters.
disable Prevents Windows from automatically mounting any new basic and dynamic volumes that are added to the system.Note: Disabling automount can cause failover clusters to fail the storage portion of the Validate a Configuration Wizard.
scrub Removes volume mount point directories and registry settings for volumes that are no longer in the system. This prevents volumes that were previously in the system from being automatically mounted and given their former volume mount point(s) when they are added back to the system.
noerr For scripting only. When an error is encountered, DiskPart continues to process commands as if the error did not occur. Without this parameter, an error causes DiskPart to exit with an error code.


To see if the automount feature is enabled, type the following commands from within the diskpart command:


To enable the automount feature, type:

To disable the automount feature, type:
