I've had my Desire for about a month and a half now, but have been having problems with my SD Card, which seem to be getting worse. Intermittently I get a message saying something along the lines of 'the backup can't complete as the SD card can not be accessed'. I also sometimes experience the problem trying to snap a photo, only to be told that there is no SD card (which of course is really bl**dy annoying). When this happens I can still see the card using the ES File Explorer, including seeing the contents, but if I try to open a file (e.g. a photo) I can't view it. I have searched the forums/the Internet and the general recommendation seems to be to reformat the card which helps for some people. Someone also suggested the SDMount widget to re-mount the card when it happens. I've tried using two different cards (the included 4GB card + a 16GB Sandisk card), reformatted both several times, but I still get the problem. I ran a memory card test tool on the 16GB card and couldn't find a problem. The only way I've found to get access back is to unmount the card and then restart the phone. Does this mean my phone is faulty, or could it be some software causing the problem? Is anyone else having the same ongoing problem?
