Yus. I'm always invited to play with the RAID.
However, switched it on and off a few times, shoved things around, prodded bits, tightened things, loosened things - even drank coffee and stared at it for a while.
Pressed power button again. "Zing!!" All back to normal.
(Whatever 'normal' is).
Things like these scare me. Finding "intermittent" faults is a challenge.
Finding permanant faults via logic I love - finding intermittent faults on gear that has a mind of it's own..........keep me away from sharp objects and alcohol.
