Logical Block Addressing

<storage> (LBA) A method used on IBM PCs and compatibles to increase the size limit for a single hard disk from 528 megabytes to 8.4 gigabytes. An addressing conversion is performed on the IDE disk controller card. Most modern PCs will select this mode automatically, some older PCs allow you to select LBA mode manually in the BIOS.

[What sets the limits? Does LBA only affect IDE?]
