I\'ve experienced my SD card toggling from being rw-mounted to ro-mounted when I had a problem with it because of a write gone bad.
In the end I had to re-format the card. After that I experienced no problems.
# umount /mnt/card
# mkfs.vfat /dev/mmcda1

before you re-format try: fsck /dev/mmcda1 (you need to unmount it first as shown above).

I type in:
fsck.vfat /dev/mmcda1

And receive:

dosfsck 2.8, 28 Feb 2001, FAT32, LFN

Got 0 bytes instead of 512 at 0

I get the SD card mounted read-only occasionally if I remove it while the Z is powered on, or remove the card without software ejecting it.

To fix it I software eject the card, put the Z into suspend mode then power on again - this almost always remounts the SD read-write.

If not try rebooting, and if that don\'t work try fsck (or check for errors in windows using a card reader), if that still don\'t work then you\'ll need to try reformatting.

Not I only have a C760 so don\'t know about the 5x00 models
