harddisk partition tables, it automatically checks and repairs partition;table error.;;  Partition Table Doctor provides very useful functions: such as;backup partition table, restore partition table, rebuild partition table.;So much as, it permits you to configure every parameter of the;partition table.;;  In addition, Partition Table Doctor provides some other useful;functions: check partition, active partition, hide partition, scandisk,;rebuild MBR(Master Boot Record), set password for harddisk, unlock;harddisk, view sectors, edit sectors, backup sectors to file,;restore file to sectors, copy sectors, fill sectors, and so on.                                 ·                ▀               √  ▌▌▀²▌                        ⁿ¬¬¬»               ²▌            ²▀²▀▀          ·  ▀         #D║¼ñVz▌▌             ²▀  ▌▀      ²▀  ▌▌▀                         ▌ ²▌   ²▀            ²▀        ▌                   ²▀¡»▌                   Notes for Using And Running:;;  
You'd better run Partition Table Doctor under pure MS DOS environment,;
because partition operations are independent of operating systems and;
very 'low level', some function such as fill sectors only run under;
pure MS DOS environment.;;
  Of course, you can run Partition Table Doctor under the MS DOS;
prompted window in WINDOWS 9x or WINDOWS ME. 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. They are saved in memory buffer instead.;;
  While complete and there are no errors, you can send out a 'apply';
command use CtrL+S key or select 'Save' from menu 'General'.
 Then;Partition Table Doctor write all your operations to harddisk one-off.                                 ·                ▀               √  ▌▌▀²▌                          ⁿ¬¬¬»               ²▌

  If you are not sure about your backup file, we strongly suggest you;
choose 'VirtualDisk' choice , this choice uses memory instead. So you;
can confirm that the partition table is just which you want and apply;
the partition table by press 'Ctrl+S' key or select 'Save' from 'General';
menu later. But if you choose 'VirtualDisk', boot sector of every;
partition will not be wrote !;;
Rebuild partition table:;;
  If partition table was destroyed by virus or other reasons, this;
function can help you to rebuild the partition table by searching the;
boot record information of every partition. The searching process can;
run with 'Auto' mode or 'Interactive' mode. Auto mode will automatically;
save every partition found. That's, you need not control the searching;
process. This mode is the same with most situation.;;
  While, Interactive mode allows you to select 'Yes' or 'No' for each;
partition Partition Table Doctor found. When the partition table rebuilt;
by Auto mode is not correct, you can try Interactive mode. In searching;
process, the searched partitions will be displayed on screen in time. But;
Partition Table Doctor will not automatically save the rebuild result;
when complete. So, you can search time after time till the correct;
partition table is rebuilt. The "Rebuild" function item is under;
'Operations' menu.;;
Set password for harddisk:;;
  Set password for harddisk realize direct physical disk access and IO;
port. Set password for harddisk encrypt partition table, and rewrite MBR;
(master boot record), User must enter the correct password to decrypt;
partition table and start the system. Maximum password length of support;
8 characters.;;
  When harddisk locked, you cannot use floppy or cdrom  boot the;
system. It's a safe for encrypt disk and protect privacy. This feature is;
designed for PC and Microsoft operator system.;;
  If you want to change or remove password for harddisk, you must enter;
old password.;;
  Please remember your password clearly as possible as you can! If you;
forget password, it's very difficult to unlock system !;;
Rebuild MBR (Master Boot Record):;;
  Use this function to manually rebuild the master boot record (located;
on cylinder 0, head 0 and sector 1) when it was destroyed and the;
computer couldn't boot from it. Partition Table Doctor will check and;
rebuild the MBR automatically.;;
Scandisk:;; 
  This function is used for checking bad sectors on one harddisk.;
It checks partitions not by 'clusters' and doesn't labeled out the bad;
sectors on FAT(FAT32) partition. Partition Table Doctor will check every;
sectors and display when it found a bad track (head). While complete,;
a bad sectors list file 'scandisk.txt' will be created.;;
Unlock harddisk:;;
  This function is used for unlock harddisk which had been locked even;
if use bootable floppy or cdrom cannot boot system. You shoud insert;
an empty 1.44M floppy disk.;;

partition to the destroyed boot records for recovering. To copy, you;
must enter source and destination position sectors and the number;
of sectors want to be copied. The maximum of number sectors is 2000.;;
Fill sectors on partition:;;
  This function can fill all sectors on current partition with 0. Fill;
sectors on partition only run pure MS DOS environment.;;

  Partition is a piece of disk space marked to belong to some operating;
system. 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.
