    Insert card and execute fdisk -l command. Post output here.
    It is amazing what you can accomplish if you do not care who gets the credit.

    That image isn't very easy to read. Could you copy/paste the output here?

    I don't know if this is a similar situation.
    I used dd to put an image on to a SD card, tried mounting the partition and got similar errors.
    "fdisk -l /dev/sdc" showed the partitions, but they couldn't be mounted.

    I had to remove the reader and reinsert it, then I was able to mount the partitions.

    I had noticed that if I prepared a SD card I could only mount it on another PC but this time I decided to look closer at the problem.

    Normally I successfully format SD ,SDHC memory cards using Gparted in Linux.
    When using Gparted ,you first might have to remove anything on the card ,making it ´unallocated´ After that the card can be re-formatted in whatever format you wish ,just like any Hard Drive
