This problem is confusing me. I have been jumping through hoops trying to solve it. Basically my sd card says it is full so I can not download anything. I can access the card and I deleted gigabytes of stuff off of it even though it was not full to begin with. Sometimes it reads 73kb free. I am rooted and had been testing a number of different roms in the past week until this happened. Tried all of my backups, wiping data and cache, loading a fresh rom. No dice. Unmounted card removed and put it back. Same issue. Any suggestions? I have tries to search for someone with similar issue with no luck.
