CHS

Short for Cylinder-Head-Sector, CHS is the access mode used by computers to assign addresses to data on computer hard disk drives. This access mode was used with early hard disk drives (hard disk drives below 550MB before 1990). Today, this mode has been replaced with ECHS and LBA.

• Additional information about why your hard disk drive may only be detected as 504MB, 528MB, or 540MB can be found on document CH000182.
