Fairly simple question I think:
I have three SATA HDDs in my system.  The mobo does have the one HD LED connector that I use, however I would like to see each individual HD have it's own LED.

Question: Is it possible for each SATA HD to have it's own separate LED?

Not natively in Windows.

Try an aftermarket product like http://www.hddled.com/

I use Tray Status to provide indicators when there are no physical LED's, but it does not monitor multiple drives.

>>  Question: Is it possible for each SATA HD to have it's own separate LED?

An interesting question.

Surprisingly yes.

Two YouTube tutorials:

https://www.youtube.com/watch?v=QgFIEegpWbQ (in German and involves making/or purchasing a circuit board [from a quick view of the video])

https://www.youtube.com/watch?v=7grZYJdEIPw (a method I would not recommend)

The cables from cooldrives.com appear to be the least intrusive and safest option to pursue.  But apparently, you can't simply just put an LED on the Pin 11 Output.  Is there any information about what resistor needs to go on it?

I think that depends on the voltage of your LED.  The line appears to be 5 volt.

So if you LED pulls 2 volts you'd d need a resistor to handle the excess 3 volts.  But you are probably best to ask someone else rather than me on this point.

Did you try the app I posted?

If you tap the power line to the drive, all you get is a "drive has power" light which is probably a given.
If you tap a data line (for an activity light), you could change the drive termination characteristics.

I am trying the app from http://www.hddled.com/ now.  It appears to be adequate.  Thanks!
