Hi Timothy,
Does fdisk not like large disks?
fdisk cannot handle drives >2TB (you can use parted to work around this, using gpt label rather than msdos). However, this should not affect you, as your drive is well within fdisk's limits. Do you have any idea why the system type is Speedstor instead of 'Linux' ? That would slightly concern me, though you could always change it in fdisk - make a full backup first, of course.
