hello. Sorry in advance; this is long. My dstt is the newest generation that dx just started selling. I've had it for just a few weeks and it's only recently been giving me occasional minor problems, then it suddenly became vicious... I was using a 4gb japanese microsd that I bought some time ago for my blackberry, the card's never given me problems. Anyway, I recently had a couple issues with files randomly corrupting and I had just resolved that with a lengthy backup and reformatting (which thank god I backed it up!) I was already using the latest official firmware. Well, just now I powered up my ds, I went to load a backup and I got the dreaded dsttmenu.sys error. I restarted my ds, and the little loading screen got stuck. I figured maybe my card was too full so I stuck it in my pc, both via usb and also through the built-in card reader, and the computer won't read it at all, it's like I have nothing inserted so I can't reformat. Has anyone heard of a dstt frying a microsd? The only thing I changed since the last time the unit powered on normally was I updated the usercheat.dat since the one included with the dstt firmware is outdated and almost completely in chinese and japanese. I'm going to get another microsd (obvously) but I'm worried this will happen again. Any ideas?
