HDD LED CONSTANTLY ON

[amanua]

I noticed forthe second time the hdd led on a filesrv with 80gb hitachi hard drive mirrored is constanly on for hours even when users on the net work are not accessing files.
I checked the events viewer but did not notice any error message and users are not complaining of any problem
Any idea to reverse this problem

Do you have a virus scanner running???? Could be that it is scanning a lot of files, constantly??

Does the LED flicker when there IS hard drive activity? If so the LED is probably plugged into the MOBO wrong.

I checked SATA cables and the hdd led and everything was fine and there was no unusal noise from the drives so I contacted the tech support for Hitachi and this is the answer they gave me through chat( Yes our Newer drives only require 3.3V for the LED power instead of the 5V the old drives used to.
JD: if you use a 5V source, it sometimes burns out the logic circuit
JD: it will not affect the drive's function
JD: It does not affect the function of the MB or the HDD...
Well this is what the manufacturer says so I have to take their word
