Corrupted SD card...

So I've had a supercard SD for quite a while... and had no problems. Then one day, either my card reader or the SD card itself acted up (It would work like normal, read it, then act like the card's removed), and I came up with the dumbest possible solution: "Hey! Maybe I should defragment it!" So that got to about 3%, and then my card reader signaled that no card was plugged in, even though my card was still in there. When I removed it and put it back in, the card reader just kept blinking like it was reading/writing it... When I stuck it back in my SCSD, it worked like nothing was wrong, but something was wrong... when I tried to write to the card using some of my various homebrew apps, they crashed and upon resetting directories dissappeared... I believe (or, at least I hope) that it's just the filesystem that's corrupted and not the card itself. :|  


ANYWAY... long story short, I need to know if I can manually command my card reader to perhaps dump the card so I can try to reassemble the filesystem. If that's not possible, then I need to know if I can format it (zap it with a watch battery, maybe) because accessing it (read: clicking it) from "My Computer" causes the system to hang until I remove the card.

Anyone up to it? Thanks in advance.

Not sure how you could recover crap on it but try formatting it with the following:

Start > Run > type "cmd" > Format E: (Replace E: with drive letter)

Obviously he will lose his game sav data if he formats his SD.

Try winhex or some other FAT repair/recovery tool before you format.

Thanks for your help, guys, but the thing is I can't even access my drive. It doesn't work... it might even be that I ruined/destroyed something in the card itself...

Like I said in my first post, I need to manually force commands to the card reader. Does anyone know enough about usb to help me?

If you're curious, I have a Supercard SD, one plain, non-knockoff Sandisk 1gb card, and  a Stratitec "25-in-1" card reader you can find in Sam's Club (well, in the USA)

Gimme some advice, knowing that standard methods like just clicking the drive and command prompt won't work. Thanks.

EDIT: I tried your advice, bitbit. I'm downloading a shareware tool called "GetDataBack" right now. They say that it works even with drives not reconized by windows. My fingers are crossed...

EDIT 2: Even with this supposedly powerful recovery software, I still encountered the exact same problem when it was scanning for drives: it would freeze until I removed the SD card... Since my supercard SD can still read the card, maybe I can use the DS to format it, just have a program write zeros to the SD card or something through wireless multiboot... either that, or my sd card's completely ruined... :cry:

EDIT 3: Yeah, yeah, 3 edits in just one hour... I came up with the brilliant plan of using REIN to copy my save files, one by one to a seperate flashcart using a game I don't really care about because reading from the SD still works on the DS. Neat, huh?
