I tried mounting it via USB to my computer, but it acted like the card didn't exist, either. When trying to format, it just said "Insert a drive in slot G:". I think this one is dead, so I sent it back to Amazon and asked for a refund. Oh, and I bought a Kingston Transcend, what rubbish (I've owned a 2GB SanDisk for a year and a half, and I can't tell you how many times it "should've" corrupted, but never has. Transcend? It took all of three days...).

Edit: How could I forget, thanks for the help bun and OSEmu!
