NetServer E800 - High shreiking beeping noise

[CA1343451]

I was given the NetServer E800. I formatted into window xp and everything worked well for a while until I opened up the cover. I opened up the cover and realize that there are two hard drives inside. I removed one of the hard drives and turned the computer on to see which hard drive actually has window xp installed. Well, the first test didn't work so I inserted the other one back. When I turned on the computer again (both hard drives are connected), there is a high shreiking beeping noise coming out, beeping continuously. The computer is still operating normal, but somehow the unbearable noise won't go away. Does anyone know why?

Thank you

Could it be that the system has a NetRAID array controller ? It will beep if a drive fails (or is removed).

If there is a NetRAID controller then you should see a message during POST to press CTRL-M. There you can access a menu where you can configure the controller (incl turn off alarm)
