Sample Chapters from book DATA RECOVERY WITH AND WITHOUT PROGRAMMING by Author Tarun Tyagi

The figure given next shows the MBR of a Disk with FAT32 partitions. The highlighted area of 64 bytes in the end of the figure represents the Master Partition Table of the MBR.

The Encoding for the Starting and Ending CHS is as Follows:

  • At offset 00H, 80 (Hex) represents that the partition is an Active partition.
  • At offset 01H, 01 (Hex) represents the Starting head number = 1.
  • The combination of two bytes at offset 02H and 03H form the Starting sector
    and cylinder number of the partition as per the encoding given next:

Bits 7 to 0 For Cylinder Number

Cylinder Bits 9, 8

Sector Bits 5 to 0

Cylinder Number = 0000000000 (B) = 0

Sector Number = 000001(B) = 1

Thus Starting C-H-S of the partition= 0-0-1.

Similarly the Head number for the Ending of the partition is FE (Hex), which is 254 and the Encoding for the Ending Cylinder and Sector number of the partition have been given in the next table:

BDH (Byte At Offset 07H)

BFH (Byte At Offset 06H)

Bits 7 to 0 For Cylinder Number

Cylinder Bits 9, 8

Sector Bits 5 to 0

Cylinder Number = 1010111101 (B) = 701

Sector Number = 111111 (B) = 63

Thus the Ending C-H-S of the Partition = 701-254-63.
