AVAILABLE. (see below)
|
|||
|
|
|
|||
|
|
Possible translations:
|
|||
|
|
This translation is generally acceptable, as
|
|||
|
|
is, for non-DOS operating systems:
|
|||
|
|
2099 cyl, 16 heads, 63 sectors = 1,083,285,504
|
|||
|
|
|
|||
|
|
Other FULL-CAPACITY solutions for DOS operating
|
|||
|
|
systems include third-party drive preparation
|
|||
|
|
software, system BIOS which supports LBA mode
|
|||
|
|
or bios driven host adapters. Otherwise,
|
|||
|
|
capacity may be limited to:
|
|||
|
|
1024 cyl, 16 heads, 63 sectors = 528,482,304 (Master)
|
|||
|
|
1024 cyl, 16 heads, 63 sectors = 528,482,304 (Slave see Dual
|
|||
|
|
Drive emulation jumper)
|
|||
|
|
|
|||
|
|
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.
