Won't write to disk
Camera appears to take the picture, but then doesn’t write to disk. Have tried new disks, ensured the card is not locked. Did this before, worked for a while, now not writing to disk again. As a diagnostic effort, took a picture and then after 15 seconds attempt to power off, message says wait for the camera to finish writing to disk, pauses, then shuts down as if completing the write, then no picture is on the disk. Battery if charged, everything else seems to be working correctly, has the latest firmware (1.1), have reset to factory specs, reduced the picture size, etc.
