I went into "disks". The other drive wasn't listed, but in Gparted it  
showed up correctly. The fdisk command:
fdisk -l /dev/sdb also worked.

Can /home also be shared between 2 Linux distros on a triple boot?

Can I create these partitions by booting from the live-CD? I know  
Gparted is there, but I am wondering if it is safe doing it from a

Thanks. What I was thinking of was how you would propose that I  
divvied up 80 GB on an extra internal HD, where around 10-20 should  
be used for sharing between the booting systems?
