WebMy understanding is that, for compatibility with older IBM-PC compatible BIOSes such as your system, every IDE drive with over 8 GB of storage uses fake cylinder-head-sector values of (512 bytes/sector)× (63 sectors/track)× (255 heads (tracks/cylinder) )× (1024 cylinders)=8032.5 MiB -- the so-called "8 GB limit". WebCHS addresses can be converted to LBA addresses using the following formula: LBA = ( ( C x HPC ) + H ) x SPT + S - 1 where, C, H and S are the cylinder number, the head number, and the sector number LBA is the logical block address HPC is the number of heads per cylinder SPT is the number of sectors per track Documentation / Reference

WebAnswer (1 of 3): Most modern hard drives do not record the same number of sectors on each track at the inner cylinders versus the outer cylinders, as much more data can be fit onto the outer ones due to their larger linear distance per rotation.
