Default Pro Tools 9 -Mackie Onyx 1640i mixer digital noise issue

Hello,
I'm using pro tools 9 on my macbook pro OS 10.6.8.
My Mackie Onyx 1640i just arrived.
I hooked via fire wire, assigned the tracks.
I hit play back on one of my test songs, and it sounded okay but about halfway through the song, what sounded like some loud digital noise began to appear along with a helicopter sound.
I'm using 96k 24 bit resolution.
In the macbook - I set the audio prefs to be 96 - 24 as well.
In pro tools, I reset the buffer and restarted.
The song sounded okay again but then the noise appeared once more.
Does anyone have a clue as to why this is happening?
Thank you.

Hey all,
Just letting you know that I resolved the digital noise issue. When I plugged the 1640i directly into the mac book pro's fire wire port (using a 400 to 800 cable) and chained the ext hard drive to the mixer, the digital noise issue went away.
I'll probably get a firewire 800 hub and not use the chain method but for now, it works for me.
Take care-
mc
