Dead SD card ?

Post by [email protected] »

Hello,
I soldered an Arduino data logging shields a month ago. It worked fine for a while and recorded some temp from my fridge.
Then it stopped working, and the SD card now shows :

Free RAM: 1110
error: card.init failed!
SD error: 1,0

This 1 Gb SD card is not recognized any more by any computer or camera I have. (It cannot mount so impossible to format it).
The shields works fine with another SD Card.

I have 2 questions
My SD card seems to be dead, is there a way to recover it ?
What are the things to do or to avoid to keep the SD Card alive ?

Thanks.

JL.

Hello,

Thanks for your feed-back, if you have never heard of such damages and there is no particular precaution to take, then it might be particular to my case. I feared I had wrongly handled the card by removing it while being written to or something of that kind.
I have to admit that there were some water drops around the shields in my fridge maybe some condensation fell on the shields and short-circuited something.
The shields still works though which is the most important !

I have been unable to reformat it because it is not 'recognized' by my computer or camera.
I will see if some suggestion to revive it is posted here ;)

sorry to hear that, yes removing the card during write is not suggested. we'll keep track of these kinds of errors in case it happens again

I debug SdFat by hot inserting and removing about twenty cards in a sketch that does a number of tests then asks for the next card. I have not had any problems so the Data Logging shield is not too likely to damage cards when you remove/insert cards with power on.

But never say never.
