I stupidly took my sd card out when my gp2x was on then i put it back in. Now neither my gp2x or my card reader bring anything up. It won't work in my camera either. Is there a way of fixing a corrupted sd card?
 
I don't think taking the SD card out when the GP2X is running is bad, I have done it a few times. It is just bad to take it when it is being written to (and possibly read from, not sure about the updates).

Just format it. If you pulled it out during a write it can corrupt the data, a format will fix all.
The card reader can't see the card to be able to format it.

what do you mean?, you can see the card, but cannot format it?

No, I put the card in the card reader i click on removable disk I and it tells me to insert a card. The reader is not reading anything even though I put the card in.

try putting the card in the reader, then plug the USB cable in.

Yeah it's plugged in, its reading other cards fine

No, I mean take the USB cable out, stick the card in the reader then plug it back in. I had a cheapo card that strangely wouldnt work unless I did that (my other ones are fine)

Sadly it didnt work but I was optimistic for a bit so thanks for the help

Taking the card out while it's still turned on (or before/during sync) can corrupt the SD card's partition table. Don't ask me why, blame gamepark.
Since windows expects there to be at least 1 partition on it, it doesn't see the card.
Your card is probably not broken. Just fix the partition table AND reformat. (some cameras can do this for you)

How to do this in windows is your problem - I don't have a clue.
In linux, just let fdisk rewrite the partition table (it's not entirely gone) and run mkdosfs -F 32.
 
I had this recently happen with my card reader.

It was working fine, I was copying a large file then I suddenly got an error and the card couldn't be read by every device I tried it in.

This kind of failure seems to be common early on with cheap cards, just send it back to where you bought it or the manufacturers
 
what cardreader are you using.
the free one i got with my gp2x didnt like my card at all. in a new reader it all works fine.
try a different reader before sending anything back

Maybe the batterry light could be used as a read/write light in the future.

now that's a GREAT idea! how about it, GPH?

someone had already implemented this in a program... cant remember wich one.

hmm, maybe you could use gfoot's usb serial driver on another card, get a bash prompt with that, and then swap cards (umount first to be on the safe side, since you don't want another damaged card) and run fdisk. That should be able to repair a bad partition table.

Other than that, maybe get another 1gb card, and then use the linux 'dd' command to read the new card and copy it directly to the old one, which should make the cards almost identical.
 
You can even try the drive manager within WinXP and see if you can setup a new partition table.

VICE. It's quite neat to see in action too ;)
