drive partitions. This process verifies the information written by
the low-level format and creates file allocation tables (used to
catalog and access files). Consult your DOS manual for FORMAT
command options. During formatting, DOS system files should
be transferred to one disc partition (generally the “C” drive), so
that the system can boot off of that drive. After high-level format-
ting a drive, you can verify the usable drive capacity using the
DOS CHKDSK utility program.
Installation troubleshooting
Before calling Seagate Technical Support, please read and con-
sider all the possibilities discussed below. The suggestions pre-
sented here will resolve the vast majority of installation problems.
Warning. To avoid personal injury and damage to electronic
components, always power off and unplug the com-
puter system before changing jumpers or touching
any internal components.
•Verify compatibility. Check the documentation for the host
adapter and the drive to confirm that these components are
appropriately matched for each other and to your system.
•Verify your configuration. Refer to the drive and controller
installation guides to make sure all jumper settings suit your
configuration requirements.
•Check all cables. Make sure all cables are securely con-
nected. Ribbon cables are especially fragile. Make sure they
are not crimped or damaged in any way. Having extra cables
on hand for troubleshooting saves time and frustration. Most
cables have a stripe down one side to designate the pin 1
location. Make sure pin 1 on the interface cable connector is
connected to pin 1 on the drive interface connector and pin 1
on the host connector. Refer to Figure 1 on page 4 for the
location of pin 1 on the drive interface connector.
