I don't really know what these mean. I thought the normal failure mode for SD cards was to go read-only, so I'm a bit lost.
Any suggestions to recover the images at least? Or is it totally dead?
I would try another reader - I have had cards that refused to be read in one laptop, but worked fine in another - maybe even try a camera? I have also had varying experiences with formatting routines - a card could not be read in my laptop, nor formatted, but in my Nikon camera, it could be formatted (vfat), and then worked fine.
Thanks everybody so far. Per, yes, I will try it in another camera. Carlos, yes sdc is the dodgy SD card. I'm not that gaga yet! :) Josef, hmm maybe. See below. jdd, Why does it want to be root, to read a device mounted under my ownership? Anyway, I tried to mount the card again and this time it succeeded. But there are some read errors.
