Hard Disk Drive C:
Hard Disk Drive D:
Move the cursor to these fields via
and select a hard drive type by pressing
<PgUp> and <PgDn>. The hard drive types
are listed on page 64. Match the hard disk
drive parameters provided by the hard disk
manufacturer to a hard disk drive type in
this table. If the parameters for the hard
disk drive being configured do not match
type 1 – 46, select Type 47 and enter the
hard drive parameters.
If configuring an IDE drive, you must
select Type 47. If configuring an ESDI
drive, you must select Type 1. If
configuring a SCSI drive, you must select
Not Installed. Not Installed is used to
configure diskless workstations.
Type 47 can be used for both hard disks C:
and D:. The parameters for type 47 under
Hard Disk C: and Hard Disk D: can be
different, which effectively allows two
different user-definable hard disk types.
The hard disk drive parameters are:
Parameter
Type The number designation for a drive with certain identification
parameters.
Cylinders The number of cylinders in the disk drive.
Heads The number of heads.
Write The size of a sector gets progressively smaller as the track
Precompensation diameter diminishes. Yet each sector must still hold 512 bytes.
Write precompensation circuitry on the hard disk compensates for
the physical difference in sector size by boosting the write current
for sectors on inner tracks. This parameter is the track number
where write precompensation begins.
Landing Zone This number is the cylinder location where the heads will normally
park when the system is shut down.
