WebApr 25, 2011 · The reverse calculation (to convert LBA to CHS) is as simple as this. In this numbering scheme, which is called LBA (Logical Block Addressing), each sector can be identified by a single number. The first logical sector is LBA 0, the second is LBA 1, and so on. This scheme is linear and easier to deal with. WebYou can do the calculation in the reverse direction (CHS to LBA) using: CHS tuples can be mapped to LBA address with the following formula: LBA = (C × HPC + H) × SPT + (S - 1) In order to compute CHS for a given LBA on the disk you need to know the Sectors Per Track (SPT) and the number of heads.
