- Possible Translation: 873 cyls, 10 heads, 54 sectors = 241,367,040
- Possible Translation: 536 cyls, 16 heads, 55 sectors = 241,500,160
- Possible translation: 873 cyl, 15 heads, 36 sectors = 241,367,040
-
- 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
-
- WARNING - 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.
