A friends wii (virgin, never modded in any way, about 2-3 yrs old, running 4.3) stopped reading disks. Gave the generic can't read disk error. I told them to get a "dvd cleaner" and put that in the drive. They did, it didnt help, so I ordered a new dvd drive for them. Last night I installed the new drive, put it back together, turned the wii on, and once again was given a cant read disk error (actual game, not a bootleg) Is there anything else software or hardware wise I could change/try/test that might cause this?
