Xraid help anywhere?

[JSeliski]

I need to squeak another year out of my Xraid - I have a bunch of spare parts and drives - so here I go. However I had one half of my Xraid (Raid 50 - 14 400mb drives) all of a sudden lose the green lights on one side. Swapping out controllers isolated it as a controller problem. Replaced controller - then lost one drive at the same time. Popped a new one in and rebuilt over the next day or two. NOw it says all is fine - In Raid Admin as well - all green. But the Xraid keeps cycling through the drives with the activity indicator spiking (and drives cycling) every few seconds e. No problem in accessing drives or data Here is what it is doing

Is the host reading/writing to it (Spotlight etc.)?

[JSeliski]

Yes - reading and writing fine (needless to say I am copying files off) - watching with AJA speed test shows very intermittent speeds
