After unboxing the smoothieboard, I plugged it in via USB on my Ubuntu Laptop. The SD card would not mount, so I ended up using windows, where after installing the drivers it worked fine. When I plugged in the SD card directly in the slot in my Ubuntu laptop, it mounted instantly.
I have since had time to investigate this issue and have installed Pronterface on the Ubuntu laptop, which happily connects to the smoothieboard. Via the pronterface, I am able to browse the SD card.
When I "fdisk -l" in the terminal, it lists the drive, but is not mounted. When I try and mount the /dev/sdb it returns…
mount: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so.
When I try this in Debian, it states "Does not contain a valid partition table".
