I have a Galaxy MGB Raid Pro with 2 TB of storage, and it works great. In fact, the only time it's even audible is when the disks spin up. I have them set to shut down after 10 minutes idle, and they apparently do so, but something is spooling them up every 1/2 hour or so. The high-pitched whine annoys me, as does the unnecessary disk usage. What is causing them to spool, and can I shut it off? Maybe Vista indexing?
