Ok so yesterday I got a 4GB SanDisk Cruzer Micro. I was working great, untill i noticed something. It was showing I had 3.6 GB, when nothing was in it. I took it to shool, and had to use it on one of their Macs. It is an older version. I brough it home, loaded up my stuff, and tried to save soemthing, but i couldn't. I look to see why. I had 800 or so MB. I toom out what i had, the number stayed the same. I tried to put it back in, I wouldn't fit. I was looking around a bit, and some people said there may be a hidden folder? I pluged it into my dads work laptop, and nothing showed. Is there something i can do? If it is broken, my dad will be sooo pissed you have no idea.
