g6real been working fine for me for like 2 months, but recently i got into a problem when my DS and Pc cant read the card, untill i have to blow it, anyone else got that problem too?
Instead of blowing on it, fold a piece of paper towel over a toothpick, dip it in a little alcohol, and clean those contacts. Blowing will actually transfer the moisture in your breath to the contacts. Alcohol cleans, then evaporates.
Another trick I've learned and since I've started doing it I've been having zero problems, don't use the USB extension, just plug it in directly, do it slow and gently and don't push it or force it hard against and it will work like a charm 100% of the time. Since I started doing that I've never had a single problem or anything.
