| Jul 27, 2014 at 8:20 | comment | added | vinc17 | @mikeserv Yes, this may be the problem. I don't have the SD card any longer. The camera plugged into a Mac OS X computer with the USB cable was recognized (but not the SD card alone). I didn't try the USB cable on my laptop. | |
| Jul 27, 2014 at 1:53 | comment | added | mikeserv | Though maybe if the camera is configured to only serve pictures over usb it would use its own proprietary format and screw allowing it to mount. If thats the case then i think you might wanna try plugging it into your computer. A lot of times that stuff just works and youll get the camera instantly, else you might need to install v4l2. | |
| Jul 27, 2014 at 0:44 | comment | added | mikeserv | @vinc17 - that's a good point, but maybe do that same thing with the camera. Still, most cameras will just understand and use fat filesystems. Can you mount other fats? | |

@mikeserv Actually I think that for the TV, the card was used via the camera (from which the SD card came) and a USB cable. I didn't follow this closely, but in such a case, I suppose that this may be very different (e.g. if a protocol like MTP is used). As you said, the card is probably wholly formatted with a single filesystem, otherwise I would have got at least sdb1. And that's why I said "without a partition" in the title.

| Jul 26, 2014 at 22:59 | comment | added | mikeserv | @vinc17 - I completely missed the tv bit until just now. You might have better luck with linux - the tv is probably running some embedded linux anyway - but you will need to ensure you have the correct filesystem module loaded in memory to recognize it. I'm almost certain there is no partition table on the card at all and it is wholly formatted with a single filesystem. You can probably find out by googling the tv's make and model and finding a manual on it. | |

| Jul 26, 2014 at 18:25 | comment | added | vinc17 | @Groxxda The SD card isn't recognized either by Mac OS X. It is currently being tried on a TV and it is recognized by it. Well, only 4 photos can be currently found. | |

@mikeserv Mounting /dev/sdb gives an error message (IIRC, a file system can't be found). I had also tried with -t vfat, but this didn't work either.

what does file -s /dev/sdb output?

You should mount /dev/sdb /path/to/mount. If you want partitions, make some, but it will likely be destructive to whatever is on the disk already if anything.

| Jul 26, 2014 at 14:56 | comment | added | groxxda | Can you verify the SD card works on another system? Is there any partition scheme on it (maybe GPT, fdisk only works for MBR)? You can try reading the first bytes with hexdump and see if they are all 0. | |
