Here is my setup: I suspect the reason is because FreeBSD uses the BIOS to find and boot the kernel, and most BIOS's only support 2 drives.

This could be a problem with /etc/fstab or with your kernel. You may need to compile a custom kernel for yourself, and use a line like: config "kernel" root on sd1 swap on sd1 dumps on sd1 >For some reason 'sd(1,a)/kernel' doesn't seem to work when all three >drives are enabled. My guess, is that it is looking at the 2nd drive >which is the 1st SCSI HD. It should work, but see my original statement.
