Here we go again. This is a recurring problem with the sd* drives
getting assigned in different orders with each boot.
The solution is to add a label to each of the filesystems on your
drives. You don't have to reformat as each filesystem's utilities
provides a way to do this. For ext2/3 its tune2fs and look for the
lable option in the man page. Once you label everything, you have to
change the references:
1. for boot, the kernel command line has to be root=LABEL=[label]
2. for /etc/fstab, change referennces to e.g. /dev/sda1 to
LABEL=[label].
Then reboot.

I think thats the wrong solution. That will fix the boot, but sda might be the external disk and
sdb the internal one.
I believe you can write a udev rule to force the internal disk to sda
