In the LBA addressing scheme, sectors are numbered as integer indexes; when mapped to CHS (cylinder-head-sector) tuples, LBA numbering starts with the first cylinder, first head, and track's first sector. Once the track is exhausted, numbering continues to the second head, while staying inside the first cylinder. Once all heads inside the first cylinder are exhausted, numbering continues from the second cylinder, etc. Thus, the lower the LBA value is, the closer the physic…
WebCHS conversion is a conversion between the geometric coordinate (cylinder/head/sector or CHS) of data on a disk's surface and the addressing system used by the disk's filesystem (linear base address or LBA).This conversion process is used with floppy disks as well as hard disks but this article will focus on its use with floppy disks..
