Sorry if this has been discussed on here before but I did search for about 20 minutes and found nothing relating to what I am experiencing. I get the following error when trying to take pictures on my HTC Hero (Sprint) "Unable to save file to SD card due to insufficient file permissions" I have removed and replaced the card. It will work for about 15 minutes then the same error. I also backed up everything and formatted the card. It worked again for about 15 minutes then the same error. Do I need a new card or is this a Hero hardware/software issue?
