drive type are available:
1.

preprogrammed values for hard drive types 1 through 45.
2.
Select USER and enter values into each drive parameter field.
3.
Use the IDE HDD AUTO DETECTION function in Setup.

write precompensation factor, landing zone, and number of sectors.
Drives whose specifications do not accommodate any predefine type are
classified as type USER.
