saw this once where the boot sequence determined the LED's source,
can't remember the brand.

Just a WAG, but try swapping the pin 1 & 3 connections.

Most likely the LED is tied to the PATA host adapter, not the SATA.

The HDD LED ia an IDE activity light and is supposed to respond to HDs &
CDROM activity. It is NOT responding to SERIAL IDE activity, which is poor
design or a bug in BIOS. Check for BIOS upgrades.

Thanks to everyone who replied! I have the latest BIOS (v. 2.4).
Changing the boot sequence makes no difference. With pins 1 and 3
swapped, the LED does not come on at all.

It does appear to be a defect in MSI's 875P motherboards. I also
found this thread: http://tinyurl.com/6eqdb

So I guess I will live without a hard disk LED.

Steve,

I had the same problem with an ABit board. ABit support said that was
as designed. Win2K, however seems to actvate the led??

I'm running Windows XP sp2, although I don't see why the OS would make
any difference.
