Possible translation: 1024 cyl, 16 heads, 63 sectors = 528,482,304
|
||
|
||
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.
