Barracuda 9FC Installation Guide, Rev. A 19
Warning. Information can be lost if you enable write cache and
there is a system failure (for example, power failure)
before the data has actually been physically written to
the disc.
OEM drives are shipped with write cache disabled by default to
enhance data integrity. If you want to enable the write cache,
refer to your system’s drive controller and software utility docu-
mentation. Seagate provides an ASPI utility that you can use in a
PC compatible system to enable the write cache. It is available
on Seagate’s CompuServe forum and on the Seagate BBS
(refer to “Technical support services” on page 8).
Connecting remote LEDs
You can connect remote LEDs using J6 (see Figure 4).
Connect the anode (usually the longer LED connector) to the
+5V pin, and the cathode to the appropriate LED output pin. For
example, if you want to attach an LED which lights up when the
drive is active (reading or writing), connect the LED’s anode con-
nector to J6 pin 8 and the cathode to J6 pin 11.
