Hi, Over these couple of hot days (33 c+) my external has been ftdisking and disconnecting itself and re-connecting all the time. Each time it has started doing this I have felt the external and it seems a bit too hot. The drive never ftdisks in the winter or on cooler days (today it hasn't done it once and it's been cool). Anyway, I just wondered if it's safe to carefully open it up and clean it out. I've had it for about 2 years now and haven't cleaned it out so it might be overheating because of the hot days & dust. Thanks, Craig.
