Note: There are two different revisions of the ST280A
|
|
1. If you have a 94204-xxC, then you can connect two different
|
|
model drives on the same host adapter. (i.e. a 94204-xxC and
|
|
a 94354-xxx drive)
|
|
|
|
2. If you do not have a "C" after the model number, then you
|
|
can only connect two similar Wren 2 94204-xx model drives.

Possible Translation: 1024 cyl, 8 heads, 17 sectors = 71,303,168
|
|
Possible Translation: 516 cyl, 10 heads, 27 sectors = 71,331,840
|

Possible Translation: 745 cyl, 11 heads, 17 sectors = 71,329,280
|
|
|
|
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.
