My first guess is that you don't have enough memory (64MB+) on the slave
node. But this might also be a memory or disk problem.

You should not need to physically disconnect the hard disk. Just remove
any references to /dev/hda that you added in /etc/beowulf/fstab.
However if you do have a hardware problem, disconnecting the disk might
avoid the symptoms.
