I have a KT7A-Raid system (Raid not currently used). I recently installed a
Hitachi Deskstat 80 mb hard drive. The HD light seems to be always on, even
when the system is not used. Feeling the drive seems to indicate it is
rotating. Is this a problem? At first I thought it was a large XP
transfer, but I set the swap file size to zero with no effect. The system
seems to work fine. Any thoughts?

did you try flipping the HD LED connector 180 around?

If it were backward wouldn't the LED never come on?

How about turning off the Indexing Service (or, at least, disabiling
indexing on the properties sheets for the hard disks)?

No, it would always be on when there is no disk activity. I've made
this mistake before.

Hi Fisher -

I disagree with you ..

From: http://web.mit.edu/~awozniak/Public/6.121/LED.html :

| You must also know that an led has polarity. This means that the
| positive and negative terminals must be connected correctly for
| it to operate properly. As you see in the diagram below, if the
| polarity is reversed, the LED will NOT light.

Also note: 'Out of the box' the longer leg of the LED is the positive
terminal. This doesn't serve much use when connecting case connectors
(which are usually designated by a '+' or dot on the positive connector).

I have seen it go both ways, where it never comes on and I have also seen it
where it is always on. you wouldn't think the reverse polarity would do
that but I had a SCSI add-in card that would do that when I connected the
LED to the card backwards.

Tom -

Interesting.

I always read that LEDs wouldn't work when connected backward. It was the
reason I went looking for a citation to back up what I'd read before I
posted when challenged further up in the thread.

I'll have to ask my brother, who designs hard disk logic circuits for a
living, for his take on the subject.

yeah, it would appear to be pretty straightforward... an LED has polarity
and that is that. however, I wondered if there wasn't something going on
with the circuitry on the SCSI card or something, that was contributing to
the cornfusion.

I feel better now.

Makes me wonder if some LEDs aren't really LEDs. I've been following a
thread in another group where a notebook drive (also Hitachi) has its LED on
all the time. I don't think there's any way the user in that case could be
reversing the connector to the HDD LED. Confusing things further, the
notebook is running Windows 98 .. so there's no indexing service running in
the background to muck things up.

Speaking of cornfusion... I'm hungry. Corn Fritters! Mmmmmm....

Last I looked through the radio shack catalog you can buy LEDs that
have two LEDs inside one package. One LED lights with one polarity
and the other LED lights with the other polarity. Usually this is for
bi-color LEDs but it sounds like they are using them for hd indicators
as well. I think if one takes a closer look, at a backwards installed
LED, that the LED will still flash (off) on hard disk drive accesses.

Is there a pink floyd song about rats-in-da-hood, or is it just pigs?

Hi Forrest -

Makes sense. I have an external USB hard disk enclosure where the LED is
green when power is applied and red when the drive is being accessed. I'll
have to open it up one of these days and see if it's two LEDs offset from
one another or if it's really one LED.

As for Rats in 'Da Hood... probably more Frank Zappa.
