However, I could be wrong so if I am please let me know.I read somewhere once that keeping disks spinning makes them last 10x longer. Personally, I've seen more disk failures on workstations which are power-cycled regularly than on systems which are always running. I've also seen disks work just fine while powered that just plain quit immediately after a power cycle. So you may save power by spinning the disks down, but I doubt you're saving disk life (unless they're powered down for weeks at a time). -- Rick C. Petty
