I needed a little more space on my SD card so I could take some pictures/video of an event I was at recently, so I took my MP3 file off of it and put it on my desktop. The problem is that my SD card has 1.1GB space taken up with... something I can't seem to see. All the files currently on my SD add up to 115MB yet my PC and my Hero both tell me that I only have 775 MB remaining. Then it gets a little worse. I've formatted the card 4 times now to try get rid of whatever is taking up that 1.1GB of space. It formats fine, I put my music back on and all the folders that were on it originally. I go to my music app and it tells me there's no music found on my SD. I look on my Hero... 1.1GB space taken, 775MB left. My music file is 1.6GB so that makes no sense at all. I plug it back into my PC and the MP3 file isn't even on there even though I put it on myself... 3 times. Rebooting doesn't work, formatting the card doesn't work and even when I do format it all the files magically reappear once I unmount the SD. Any new ones I put on don't appear at all. It was all working fine until this morning and I haven't changed anything at all (except I rooted it when I first got it, but there's been no problems up until now) so I'm completely confused as to what's triggered this. If anyone knows what's going on I'd love to know, thanks.
