Hi Those SanDisk drive are a real pain you can use them but you are going to have to fdisk it first there is stuff on there that stops Linux dead in it's tracks i have several of them the 4Gb ones (came at the right price) . I used fdisk on them then formatted them vfat for use in the car work fine now . Pete . -- Linux 7-of-9 3.8.6-1-ARCH #1 SMP PREEMPT Sat Apr 6 07:27:01 CEST 2013 x86_64 GNU/Linux
