Maybe I should have given an explanation of my requirements.

Basically, I have a NAS setup with 700+ disks contained within 45 drawers split over 7 frames that I want to watch the temp on.
The code queries the drawers one by one and maps which drawers are in which frames and collects the current temp(also producing a pictorial map of the system).

So the array would only ever contain a max of (7) for the frames and (1-8) for the drawers within the frames (as not all frames have the same no. of drawers).

The copying (or snapshot) of the array was for comparing against the next time the prog went to check the temp to inform me of differences.

Cheers
