Possible translation: 981 cyl, 10 heads, 34 sectors = 170,772,480
|
|
|
|
Note: A "custom" or "user-definded" CMOS drivetype may ask for a
|
|
numerical value for the Write Precompensation cylinder and for the
|
|
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
|
|
not require the old Write Precomp technique or a Landing Zone because
|
|
they are Auto-Parking is to add 1 to the cylinder value being used. As
|
|
an example: If cylinders equaled 820, then both Write Precomp and
|
|
Landing Zone would be entered as 821. Some BIOS will convert this to
|
|
65535 or -1, which are functionally equivalent to "none (not used)".

|

PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION

|
|
|
Already low-level formatted at the factory.
|
|
|
|
Since a User-definable or Custom translation geometry may be used, it
|
|
is imperative that the values be written down and kept with your
|
|
permanent records for retrieval in the event of CMOS battery failure.
