Has anyone ever had a CF card just up and die? I have a Sandisk Extreme Pro 32GB card which has somehow become completely unreadable in my C300. No attempt to reformat will work, I've even tried it in my DLSR, and even Disk Utility on my Mac. No go. Any suggestions? I'm more than a little surprised by this, Sandisk has generally been pretty reliable.....

Still under warranty?

Not sure what the warranty is, but I contacted Sandisk, and they've agreed to replace it. Still a little worrisome...... at least this happened after I had downloaded, and was going to reformat when it kicked the bucket. If it had happened before downloading, well, I don't like to think about that.
