To execute Partition; Table Doctor, just type 'ptd' at MS DOS command prompt or double hit; ptd.exe using mouse in the path of Partition Table Doctor. Also you ; can use mouse to choose 'Create Emergency Disk' from 'General' menu; to run ptd under pure MS DOS environment.;; When restore partition table to harddisk, the master boot sector will ; be overwrote. So you should 'Disable' the 'Anti Virus' option in BIOS; setup.;; When running, the partitions circumstantiality will be displayed; using chart and tables. The cylinder diagram in the top displays; all allocated partitions' position and size.;; The type and other detail parameters of partitions are listed in; a table on the middle of screen. About the meanings of these parameters,; please refer to 'About Partition Table' of Help files.;; Before operating on a partition you must select it first. To select; a partition, just click on the partition in the diagram or in the; table use mouse. And also you can use Up or Down key for selecting.;; In order to prevent mistakes, all operations except restore file; to sectors, copy sectors, fill sectors are not wrote to harddisk; immediately.

Partition table is located in the first sector (cylinder 0,; head 0 and sector 1) of every harddisk. It has information about sizes; and locations of partitions on harddisk. The partition information is; started on offset 1BEH of master boot sector. Each partition entry is; 16 bytes long. The total partition table is 64 bytes long. Then; partition table is limited to maximum 4 entries. That's, there are; maximum 4 partitions, called primary partition, can be created on; harddisk.;; But many people want to create more than 4 partitions. The extended; partition is designed for this. Master extended partition is a primary; partition. Differ from other partitions, the first sector of extended; partition is not a boot sector, but another partition table, called; logical partition table.;; Commonly, there are only two partition entries in logical partition; table. One points to a partition, called logical partition. And the; boundary of this logical partition must be limited in the extended; partition. The other entry, if needed, of the extended partition; table points to next logical partition table. Similarly, its boundary; is limited in its parents extended partition. The next logical partition; table may has two partition entries too. The one points to a logical; partition. The other points to another logical partition table and the; rest may be deduced by analogy. Therefore, many partitions could be; created in extended partition.;; Now let us have a look on the layout of a partition entry.; The 16 bytes of one entry are as follows:;; OFFSET BYTE DESCRIPTION;; 0 1 Boot label. Tell computer to boot from this partition;; 1 1 Starting head;; 2 1 Lower 6 bits(bit 0 to bit 5) is starting sector.; Higher 2 bits(bit 6 to bit 7) is the higher bits of starting cylinder;; 3 1 The lower 8 bits of starting cylinder;; 4 1 Partition type;; 5 1 Ending head;; 6 1 Lower 6 bits(bit 0 to bit 5) is ending sector.; Higher 2 bits(bit 6 to bit 7) is the higher bits of ending cylinder;; 7 1 The lower 8 bits of ending cylinder;; 8 4 Leading sectors of this partition;; 12 4 Number of sectors of this partition;; a) Boot label (offset 0):;; Most disks have one primary partition, but some people want to have; more than one operating system on their computers and therefore, have; to create other primary partitions. In order to tell the computer which; operating system is ready to boot from, one 'Active' partition is needed.; That's why partition table always keeps an indicator of the currently; 'Active' partition - the one from which the computer boots. In Partition; Table Doctor, the active partition is figured out by 'Act' with 'Yes'.;; b) Starting position (offset 1-3):;; Describes the partition's starting position, the cylinder, the head and; the sector. Also called starting CHS.;; starting head = (OFFSET 1);; starting sector = (OFFSET 2) & 0x3f;; starting cylinder = (((OFFSET 2) & 0xc0)<<2)|(OFFSET 3);; c) Partition type (offset 4):;; Indicate what file system is in the partition. For example, 06 or 0E; indicates a FAT file system. 0B or 0C indicates a FAT32 file system. 07; indicates NTFS or OS/2 HPFS file system.;; d) Ending position (offset 5-7):;; Describes the partition's ending position, the cylinder, the head and; the sector. Also called ending CHS.;; e) Leading sectors (offset 8-11):;; The number of sectors before this partition. If we count all sectors; on hard disk sequentially from zero, this field will exactly point to the; first sector of this partition.;; f) Number of sectors (offset 12-15):;; The total number of sectors on this partition. So the size of this; partition will be (Number of sectors)*512/1048576 MB. Liability / Warranty:;;;; If this program is used improperly, it may result in the irretrievable; destruction of all data on your harddisk!;; It is thus absolutely necessary to create a backup before using the; Partition Table Doctor.
