I've been using a Sandisk 32GB microSD for months now with no problem, but lately its been having issues. I noticed it first when I went thru and tried to delete files, then next time I looked at my sdcard those files were still there. Tried doing this using ES File Explorer, Astro, and connecting it to my pc. Same result. When I'd edit a file and try to save and go back, it was as if I had never changed the file. So I hooked up to my pc and mounted as disk drive, then tried to format the sd card on my pc and start over. Looked as though everything went fine, left my phone hooked up to pc overnight to sync my music back and when I woke up this morning, everything that should have been deleted in the reformat is still on the sd. What could be causing all this crap and how do i fix it?
