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.
The best-known floppy disk drive for the C64, the 1541 is a single-sided 170-kilobyte drive for 5¼" disks. The 1541 directly followed the Commodore 1540 (meant for the VIC-20). The disk drive uses group coded recording (GCR) and contains a MOS Technology 6502 microprocessor, doubling as a disk controller and on-board disk operating system ...
In modern versions of Microsoft Windows, changing the disk label requires elevated permissions. [5] The Windows dir command displays the volume label and serial number (if it has one) as part of the directory listing. In Unix and other Unix-like operating systems, the name of the equivalent command differs from file system to file system.
Operating systems may use the volume serial number as mountpoint name. [5] A volume serial number is a serial number assigned to a disk volume or tape volume. In FAT and NTFS file systems, a volume serial number is a feature used to determine if a disk is present in a drive or
Its DOS is compatible with the 1541, so disks written by one drive can be utilized in the other. The 1551 has no DIP switches to change the drive's device number. If a user added more than one drive to a system, they had to open the case and cut a trace in the circuit board to permanently change the drive's number, or hand-wire an external ...
The boot code in the VBR can assume that the BIOS has set up its data structures and interrupts and initialized the hardware. The code should not assume more than 32 KB of memory to be present for fail-safe operation; [1] if it needs more memory it should query INT 12h for it, since other pre-boot code (such as f.e. BIOS extension overlays, encryption systems, or remote bootstrap loaders) may ...
A: — Floppy disk drives, 3 + 1 ⁄ 2 ″ or 5 + 1 ⁄ 4 ″, and possibly other types of disk drives, if present. B: — Reserved for a second floppy drive (that was present on many PCs). C: — First hard disk drive partition. D: to Z: — Other disk partitions get labeled here. Windows assigns the next free drive letter to the next drive it ...
Data is encoded on the disk using Modified Frequency Modulation, where a one bit will result in a magnetic flux reversal on the magnetic coating of the cartridge. The last track of an RL01 and RL02 cartridge contains a table which lists all of the bad sectors on the cartridge. This track also contains the cartridges serial number.
