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).
