Format sdcard and read superblock issue

Question

I've tried to format my sd card with no luck so far. Everytime I put it in my card reader, Ubuntu throws back at me this error:

Error mounting /dev/sdb1 at /media/haunted/FC30-3DA9: Command-line `mount -t "vfat" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,shortname=mixed,dmask=0077,utf8=1,showexec,flush" "/dev/sdb1" "/media/haunted/FC30-3DA9"' exited with non-zero exit status 32: mount: /dev/sdb1: can't read superblock

also I have installed gparted to see if it was detected at least, but apparently no. I can safely rule out a card reader issue: Windows 7 and the digital camera also have problems reading the memory card. Is there anything I can do?
