That could be very useful information for members who are using Uno and Yun with a Raspberry Pi B.
The Model B uses standard size cards and adapters that could explain a great deal.

Hey shiznatix, I was wondering, are you using SD-card or are you using micro-SD with SD-adaptor?I had similar problem with same example code and with same SD-card reader and I couldn't solve the problem except by using SD-card instead of using micro-SD with an adaptor.. I tried everything, but it just didn't work, though.. After I ditched adaptor, it has worked like a dream..
Yeah, I used Uno..
