* MAY REQUIRE FORMATTING AND PARTITIONING SOFTWARE. ALSO, CHECK TO
SEE IF YOUR CMOS SETUP HAS A "CUSTOM" OR "USER DEFINABLE" DRIVE TYPE
AVAILABLE.
Translation to use: 1024 cyl, 6 heads, 17 sectors = 53,477,376
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION
ZBR = Zone Bit Recording = Variable sectors per track
!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.
Seagate reserves the right to change, without notice, product
offerings or specifications. (6/26/90)
