WebSep 25, 2015 · Addressing Each sector on a drive is individually addressable which was originally done by referring to the cylinder, head, and sector (CHS) where the required data is stored. When a hard drive was installed in the computer, you needed to change BIOS settings to let it know the number of cylinders, heads, and sectors per track on the drive. http://www.data-recovery-app.com/datarecovery/lba.html

WebCHS To LBA Mapping. CHS tuples can be mapped onto LBA (Logical Block Addressing) addresses using the following formula: Where is the LBA address, is the number of heads on the disk, is the number of sectors per track, and is the CHS address. A Logical Sector Number formula in the ECMA-107 and ISO/IEC 9293:1994 (superseding ISO 9293:1987 ...
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… highland prideWebCylinder, Head, Sector (CHS) Addressing – A method of referencing the sectors on a drive, as a collection of unique cylinders, head and sector addresses.
