Hard Drive LED always on

Any PATA drives that could have their cables plugged in backwards? Does it do it in the BIOS, or only once you've booted?

Are you sure that you've got the cable to the LED plugged in to the right header on the m/b?

I do not have any pata hard drives in my computer. I do have a dvd drive but there is a notch in it so it can only be plugged in one way.

From the moment I turn on the computer the hard drive light is on, if I am going through the Bios or booting from the usb drive.

I found some documentation on where the LED cable should be plugged into so I am sure that it is in the right place. when I unplug the cable the light stays off but when I plug it in the light comes back on. There is never any blinking it is just on or off all the time.

Thanks for you quick replies.

Thanks ijack that seemed to fix the problem.

I unplugged both hard drives and the DVD from power and data and the light flashed as in normally did.

I then plugged the hard drives back in and everything seems to be working fine.
Since I don't need the DVD drive for what I am doing I will just leave it unplugged.

Thanks for everyone's help and quick replies
