i keep trying to use the "Backup DSI NAND" feature in the DSi frimware tool 2.0.0 and i dont know what to do, i tried retrying this. and it just doesnt work. Can anyone help?
did it work? im having same issue and its not working for mealright will try

with the chkdsk it said there were no issues so what do i do now?Test the SD card for physical errors with h2testw. Note that in order for this test to be completed properly you'll need to move the SD card's contents to your computer temporarily and format the SD card before running h2testw. If it gives any errors, the card is bad and should be replaced.
It would also be worth checking for file system errors with the following from the command prompt:
chkdsk x: /f
Replace the x with the SD's drive letter. Note that any errors listed with this command aren't fatal, and in a worst case scenario you can just format it if there's a ton of file system corruption (this is assuming it's already passed the hardware test above).
