Now I've fried my 2nd card. The first was a 512mb... no big deal. This morning I was watching a dvd on my n800 which was accessing my 8gb class 6 sdhc, and then everything froze. I had to reboot by taking the battery out, and when it rebooted, drive corrupted. Tried reading from my PC card reader; gave me a device I/O error. Even tried to format with several disk utils, no luck. $55 down the drain after only 1 month of use. Brand was Adata. This is definitely a prolific problem and it is causing us consumers to be the guinea pigs. How about Nokia allows us to send them the fried cards and they send back replacements of the same size??? Yeah, right??? Maybe they will always be the red headed step child of the tablet scene because of problems like this that they will do nothing about.
