SUPER P6DNF/P6SNF User's Manual
To configure an old MFM hard disk drive, you must know the drive
parameters (number of heads, number of cylinders, number of sec-
tors, the starting write precompensation cylinder, and drive capac-
ity). Select the hard disk drive type (1-46). Refer to Appendix B in
this manual for a list of the various hard disk drive types. Select
User in the Type field if the drive parameters on your MFM drive do
not match any of the drive type in Appendix B.
Entering Drive Parameters
You can also enter the hard disk drive parameters. The drive pa-
rameters are:
Parameter Description
Type The number 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.
Sectors The number of sectors per track. MFM drives have 17 sectors
per track. RLL drives have 26 sectors per track. ESDI drives
have 34 sectors per track. SCSI and IDE drive may have even
more sectors per track.
Capacity The formatted capacity of the drive is (Number of heads) x
(Number of cylinders) x (Number of sectors per track) x (512
bytes per sector)
