ST9144 family AT interface drives

This  guide  provides  installation  information  for  the  ST9051A,
ST9052A, ST9077A, ST9096A, and ST9144A drives. All drives
in this family automatically park their heads at power-down. Refer
to Figure 1.

Caution. These drives are usually installed in notebook or laptop
systems.  These  computers  require  qualified  or  factory  trained
technicians to perform peripheral upgrades. Be sure to review the
terms and conditions of your system warranty before opening the
system enclosure.

Default drive geometry

Seagate AT interface drives mimic (translate) other drive geome-
tries. If none of the drive types offered by the CMOS support the
number of heads, cylinders and sectors per track shown by the
following  table,  and  your  system  does  not  support  a “user-de-
fined” drive type, then select a drive type in your system CMOS
with a capacity which is less than or equal to the capacity given
in the “CMOS MBytes” column of the following table.

If  you  do  not  know  which  drive  types  your  CMOS  supports,
download FINDTYPE.EXE to assist in choosing an appropriate
drive type. Refer to the “Technical Support Services” section in
the front of this guide.

When specifying drive geometry to the system CMOS, different
values may be used for the Cylinders (1,024 max), Read/Write
Heads (16 max), and Sectors per Track (63 max).
