Possible translations:
This translation is generally acceptable, as
is, for non-DOS operating systems:
1057 cyl, 16 heads, 63 sectors = 545,513,472
DOS operating systems may require a system bios
that accepts larger values for the CMOS head
parameter which lowers cylinders below 1024:
528 cyl, 32 heads, 63 sectors = 544,997,376
Other FULL-CAPACITY solutions for DOS operating
systems include third-party drive preparation
software or bios driven host adapters. Otherwise,
capacity may be limited to:
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
ZBR = Zone Bit Recording = Variable sectors per track
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.
