In a DOS based disk the partition table and boot code requires only one sector, yet 63 are typically allocated for both the MBR and extended partitions because the partitions start on a cylinder boundary.
When parts of a partition table have become corrupt, it may be necessary to search for the extended partition tables.
To find the extended partitions, a search for 0xAA55 in the last two bytes of a sector could be conducted.
If a sector is found to be a boot sector of a file system, a partition table may exist 63 sectors prior to it.
