This entry restricts access to the disks in the floppy disk drives to the user currently logged on to the computer. In this mode, floppy disks are allocated to the user as part of the interactive logon process and are freed for general use or for reallocation only when that user logs off. This parameter satisfies part of the C2 security requirement that removable media must be securable. If this value entry is not added, the contents of the floppy disks in the drives will be available to all domain administrators remotely.
