Here is a brief explanation of drive specifications:
Type
BIOS contains a table of predefined drive types with certain specifications. 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
Landzone

Sector
Number of Sectors
Mode
AUTO
BIOS automatically determines the optimal mode.
Normal
The following maximum values are supported:
Number of cylinders= 1024
Number of heads = 16
Number of sectors = 64
Large
For drives that do not support LBA and have more than
1024 cylinders.
LBA
Logical Block Addressing: For drives with more than
1024 cylinders. During drive accesses, the IDE
controller transforms the data address described by
sector, head, and cylinder number into a physical block
address. This results in a significantly improved data
transfer rate.
