After adding two 500GB disks in a mirrored RAID array, our Mac Pro occasionally beeps. The beeps originates somewhere inside the machine -- not through the speakers. They seem to come at random, at least I haven't found any causality.

Anyone else noticed this? Any suggestions as to what the beeps mean?

To be complete: I have put the original 250GB in slot 3; the 500Gb disks are in slot 1 and 2. The RAID volume is the boot volume.

    Have you actually identified where the beeps are coming from? The drives or the logic board? Somewhere else?

    Then you might want to disconnect as many uneeded items such USB/FireWire devices and your speakers to see if you can then isolate the issue to within the Mac Pro rather than being cause by something external to it.

    Having external speakers won't necessairly silence the internal speaker. I have external speakers on my Quad-G5, but the internal speaker still emits the startup sound...

    I too am encountering this problem, although it is fairly infrequent. I am using speakers via the analog audio jack and I can verify that the sound is coming from somewhere inside the machine.

    I don't have a RAID setup, just a few external drives.

    I just got a new MacPro 3GHZ at work and occasionally it will beep and it is coming from inside the machine and not through the speakers. I have no RAID. It has 2GB RAM, bluetooth, Airport and a 500GB drive built by Apple.

    Same here, no RAID though.

    This doesn't sound like something good.

    i just got my MacPro today. It beeps too. i first heard the beep when i turned the system on and then found that my superdrives did not work... this was becasue i had installed another one when the machine arrived and failed to set the new Superdrive to cable select.

    i took the beep to be indicating that something was amiss with the system, and sure enough it was. Easy enough to fix, however.

    Then, just now, i heard it beep again, this time i have no clue as to why. i came on here to see if anyone else knew... As it is, i am thinking the beeping indicates some sort of error or other.
