I was not aware that the current version of the utilities can be installed on the Compaq partition.
Yes, the older versions installed there, but I do believe the newer ones do not. In any event, I once thought I needed this partition as well, but in fact, it is simply not needed.
If you need to fool around with the raid utilities, it is far easier to have a recent copy of SmartStart laying around and use it when necessary.
To summarize,
Forget about it and use SmartStart.
