It emptied itself out. I'm using a DSTT with a kingston 2gb micro sd card. I was using lameboy and I saved my progress in pokemon crystal and it froze. Then I restarted my ds and it gave me the "MENU?" screen. Luckily, I backed everything up a week ago. Should I keep my DSTT? I was planning on getting an EZ flash to go along with my DSTT but now I'm not so sure.
Your MicroSD probably became corrupted because your game froze while saving and you have to power it down. Interrupting a write to the MicroSD can cause that.
My sd card went blank when i dropped it 3 times in a row by accident somehow. I don't know much about the DSTT. By EZ Flash you mean the Ez Flash 3 in 1 right? From what i read somewhere DSTT's are pretty good. Hmmmmmm not really sure though if you should get the ez flash. That does happen sometimes.
It corrupts the whole card? I'm formatting the card right now. Before, it said the disk was full but nothing was on the card.
It corrupts the file table. The data is probably (more than likely) still there, but without the table, devices and your computer have no idea what the data is.
My dad did something with it before I formatted it. I stuck it intot eh computer and it had a single corrupt file.
There are various file recovery or undelete programs out there (I cannot recommend one, since I've never really used them) unfortunately most try to get you to buy them, and many suck.
