Yes, /dev/sda1 and /dev/sda2 are tow partitions on the same disk.
I dont know how you have formatted your second disk, but I assume you used the webGUI for it and therefore got two partitions on your second drive. So you have to do a fsck on both of them:
/sbin/e2fsck /dev/sdb1
/sbin/e2fsck /dev/sdb2
I never used a usb hub for my disks, but I assume if it's a powered hub it should be no problem to use it.
