Hi all. So...I have a microSD card inserted into my computer. The little notch is in the unlocked position and yet, it says the SD isn't writable. The last time I inserted it, it was writable but now the permissions changed. I don't know what to do. I tried verifying the disk, and it says I have to get it repaired, and when I try to repair, it won't allow me to hit the repair button. I don't really know much about the microSD other than it's 4 GB, and in the MS-DOS(FAT) format. Here's what I see every time I verify the disk: I really don't understand anything before 'this disk needs to be repaired.' On a side note, I remember the SD working before I upgraded to the Mac OSX Snow Leopard system, and ever since I upgraded my mac, it won't allow me to add anything on the microSD. I don't know if that's relevant or not. I'd appreciate any help. Thank you in advance.
