Well, if the other option is to have your system hard-reset because the PSU overloads from 12-20-24 disks spinning up at once (you know staggered spin-up is supported by disks/controllers for a reason), then the wait does not look so bad. My take on the problem: just don't spin down your RAIDs. -- With respect, Roman
