The odd's are that it's because the disks are getting re-ordered when you plug 
in and unplug the scsi disks.

Without any disks there, grub is saying "here is my disk on (hd0,0) and away I 
go"  And since hd0,0 is the right disk, away it goes.

With the other disks there grub is saying "Well, I have two disks, (hd0,0) and 
(hd1,0).  I'm told I need to boot off (hd0,0) and away I go"  But, in reality, 
your main system disk is what grub thinks is (hd1,0) and so it's booting off 
the wrong disk.
