AVAILABLE. (see below)
Possible translations:
This translation is generally acceptable, as
is, for non-DOS operating systems:
4191 cyl, 16 heads, 63 sectors = 2,162,958,336
DOS operating systems may require a translation
that uses larger values for the CMOS head
parameter which lowers cylinders below 1024:
523 cyl, 128 heads, 63 sectors = 2,159,345,664
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
Some systems BIOS have capacity limitations.
Types that have been identified are:
a 2.113GB or 4095 cylinder limitation
and, if exceeded, may cause the system to hang during boot, or
it can truncate or wrap the cylinders when auto-detect options
set in the CMOS.
DOS cannot access more than 2.147 Gbytes per partition. Create
two partitions to access the drive's full capacity.
Note: A "custom" or "user-defined" 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.
Seagate reserves the right to change, without notice, product
offerings or specifications. (04/25/97)
