While without deliberate remapping, the drive letter assignments are typically fixed until the next reboot, however, Zenith MS-DOS 3.21 will update the drive letter assignments when resetting a drive. This may cause drive letters to change without reboot if the partitioning of the harddisk was changed.
Create the proper registry keys for the host drive letter (optional, works around the host drive label override caveat); Re-create the SUBST drive to see label changes applied. Note that the LABEL command is NOT able to change the label name of a drive letter created using subst. [8] LABEL is one of several commands that only work on physical ...
Drive Letter Access (DLA) is a discontinued commercial packet writing application for the Microsoft Windows operating system that allows optical disc data storage devices to be used in a manner similar to floppy disks. DLA is a packet writing technology for CD and DVD media that uses the UDF file system.
The JOIN command attaches a drive letter to a specified directory on another drive. [11] The opposite can be achieved via the SUBST command. The command is available in MS-DOS versions 3 through 5. It is available separately for versions 6.2 and later on the Supplemental Disk. [1]
vol [Drive:] Arguments: Drive: This command-line argument specifies the drive letter of the disk for which to display the volume label and serial number. Note: On Windows, the volume serial number is displayed only for disks formatted with MS-DOS version 4.0 or later. OS/2 allows the user to specify more than one drive.
RAM drive software allows part of a computer's RAM (memory) to be seen as if it were a disk drive, with volume name and, if supported by the operating system, drive letter. A RAM drive has much faster read and write access than a hard drive with rotating platters, and is volatile, being destroyed with its contents when a computer is shut down ...
At startup, device drivers opened this file and assigned it a separate letter. Frequently, to avoid confusion, the original partition and the compressed drive had their letters swapped, so that the compressed disk is C:, and the uncompressed area (often containing system files) is given a higher name.
Because DOS applications use these drive letters directly (unlike the /dev directory in Unix-like systems), they can be disrupted by adding new hardware that needs a drive letter. An example is the addition of a new hard drive having a primary partition where a pre-existing hard drive contains logical drives in extended partitions; the new ...
