Here is a brief explanation of drive specifications:
_
Type: The BIOS contains a table of pre-defined drive types. Each defined drive type
has a specified number of cylinders, number of heads, write precompensation factor,
landing zone, and number of sectors. Drives whose specifications do not accommodate
any pre-defined type are classified as type USER.
_
Size: Disk drive capacity (approximate). Note that this size is usually slightly greater
than the size of a formatted disk given by a disk-checking program.
_
Cyls: Number of cylinders
_
Head: Number of heads
_
Precomp: Write precompensation cylinder
_
Landz: Landing zone
_
Sector: Number of sectors
_
Mode: Auto, Normal, large, or LBA
_
Auto: The BIOS automatically determines the optimal mode.
_
Normal: Maximum number of cylinders, heads, and sectors supported are 1024, 16,
and 63.
_
Large: For drives that do not support LBA and have more than 1024 cylinders.
_
LBA (Logical Block Addressing): During drive accesses, the IDE controller
transforms the data address described by sector, head, and cylinder number into a
physical block address, significantly improving data transfer rates. For drives with
greater than 1024 cylinders.
