I recently got a microSD card for a music player, I've tried to mount this on my computer to transfer music but have got the following error:

Unable to mount 127 GB Volume

Error mounting /dev/sdb1 at /media/blank/9C33-6BBD: Command-line `mount -t "exfat" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,iocharset=utf8,namecase=0,errors=remount-ro,umask=0077" "/dev/sdb1" "/media/blank/9C33-6BBD"' exited with non-zero exit status 32: mount: unknown filesystem type 'exfat'

I'm trying to mount the microSD via a usb adapter - I've tried 2 different adapters with no difference. My system is Ubuntu 14.04.

I've run

lsusb
sudo fdisk -l 

and the results are:

Any pointers as to what the issue is and how I can resolve it?

The problem is that your SD is formatted with exFAT, which Ubuntu does not support natively. You have to install some extra packages to gain access to exFAT volumes. Please follow this answer here.
