Class OzDosFormatDisk

  • All Implemented Interfaces:
    DirectoryEntry
    public class OzDosFormatDisk
extends DosFormatDisk
    Manages a disk that is in OzDOS format. This is basically DOS 3.3 except that the disk has two volumes of each 400K. Logical disk one takes the first part of the block (bytes $000-$0FF) while the second logical disk takes the second part of a block (bytes $100-$1FF).
    Created on Dec 16, 2002.

      • OZDOS_DISK_1

        public static final int OZDOS_DISK_1
        Use this indicator to work with logical disk #1. It is essentially the offset into the block.

        Create a OzDosFormatDisk.

      • getLogicalDiskNumber

        public int getLogicalDiskNumber()
        Returns the logical disk number. This can be used to identify between disks when a format supports multiple logical volumes.
