Fried SanDisk 32GB Class 10

Crud. I shot 24 GB worth of footage on my GH13 using a SanDisk 32GB Class 10 card. The card was formatted and tested. I'd used it twice before.

Everything looked fine when I opened the card, but then part way into offloading it onto an external hard drive I got an error message. When I opened the card I got the screengrab included. Disk Utility could recognize it needed to be repaired, but its repairs were completely ineffectual. :furious3:

I use a Mac with Snow Leopard.

I can't think of anything I did wrong, unless I didn't pay enough for an SD card reader (about $10). Was it just my turn to get the shaft or is this an inherent risk of using SDHC cards?

Finally, I'm assuming that the card is compromised, even if I reformat it. Can't trust it right?

You need to use proper low level tools.
Some are for repairs (allow to get files from damaged cards).
Others allow to check physical state and mark bad sector if required.

Thanks Vitaliy. I'll research this. I'm hoping problems like this are rare.
