Access LED indicators of TeraStation Live HS-DH0.0TGL/R5

[hhnguyen]

I have 2 units of TeraStation Live HS-DH0.0TGL/R5.
If no one is using these 2 Terastations, on one unit, the Access LED indicators (all 4 of them at the front of unit) keep on blinking like crazy. While on the second Terastation, none of these are blinkings. On the Terastion, where the Access indicators are blinking, what do these mean? Are all hard drives are being accessed? Is some sort of disk scanning taking place? If that's the case, how do I turn it off. I don't want the hard drives to wear out prematurely due to constant running. Thanks for your help.

Do you have the media server (pcast) enabled on one and not the other?

I don't use the Media Server feature on either.  Any way, I just double checked.  The settings of the Media Server are the same on both units. The Media Servers are "enabled" on both.   I guess these are the default settings.  I was trying to attach a pic of these settings but could not figure how.  Anyway, any other idea?  Thanks.
