I've just had SD card errors for the first time and don't know what they mean exactly nor how to investigate further. The SD card was in a wildlife camera, which said there was an error. I thought it might have become full. I brought it back to my computer and put it in the card reader. Nothing shows up on screen (it normally opens a dialog box that offers to open my file manager when I insert an SD card). I see repeating blocks of messages in the journal: Jun 25 12:57:54 acer-suse kernel: sd 5:0:0:0: [sdc] tag#0 FAILED Result: hostbyte=DID_ERROR driverbyte=DRIVER_SENSE Jun 25 12:57:54 acer-suse kernel: sd 5:0:0:0: [sdc] tag#0 Sense Key : Hardware Error [current] Jun 25 12:57:54 acer-suse kernel: sd 5:0:0:0: [sdc] tag#0 Add.

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?
