Wiikey installed no problem and using Verbatim DVD+Rs (Taiyo Y) @ 4x - no DREs at all (burnt with LiteOn multi, dumped with LG). However, when I put my backup disc in, I hear a clicking sound (maybe 2x) when the disc is being read. After the disc loads, I don't get it again. I'm happy with everything else but wondered if this is damaging my Wii drive at all? I suppose I could backup on DVD-R if this helps but I usually only buy DVD+R and I have plenty surplus. Anyone can reassure me? Thx.
