2 days ago I rebooted my n800 and when it came back on it said that the card was corrupted or needed to be formatted. I have one of those 8gb Transcend, I've only had it for 2 weeks now. I tried formatting it in but now it's indicating that it has 492 KB of free space. It's not showing up when I put it in the laptop, it shows up when I connect the N800. Any idea what's wrong with it? Please help. Thx!
