WebPartition Table/Master Boot Record: CHS Addressing. After the partition table has been identified, the user can proceed with Cylinder, Head, Sector (CHS) partition layout. The CHS model was the first defining structure that was developed for partitions, but due to size limits, it was replaced by Logical Block Addressing (LBA), which controls ... WebMay 6, 2012 · LBA = ( ( (cylinder number * heads per cylinder) + head number) * * sector per head) + sector number - 1 Working from left to right, the first part of the equation converts the cylinder number to the number of heads required to jump; the next part adds the current head number to that and converts it into a number of sector.
