BTW that above reply applies to my lacie 2TB array regarding data transfering, no problem with my lacie 250GB HHD (non array) transfering lots of data.
regarding using a UPS for my external HHD storage. you say power failures/spikes are a good source of problems. i've been using it for a while now, and i only turn it on to transfere data to or fro, eject it from the desktop and turn it off, leaving it connected to power and the computer.
