Hi! This problem has not been solved up to now?
I have 4GB SanDisk Cruzer Fit from hackshop. I tried partition and format (minitool partition, gparted, fdisk, win 7 tool, gnome-disk-tool on ubuntu 12.10, backtrack5r2) on guide Darren and Spikey D, but the symptoms are the same as described in the topic :( In ubuntu and windows over extfs - this usb mount and work correctly.
I test this problem on 2.7.0 and 2.7.7
