Im having some issues with booting/detecting additional hard drives on the Mediasmart EX470. Heres what Ive done so far...

1. put hd into pc and installed ubuntu server
2. put hd into MSS and changed eth0 to be the MSS NIC by default
3. I shut down and put in another hard drive in slot 2 (ex4, new format and no data)
4. I boot up and nothing happens... I attach a keyboard and hit enter a couple times incase of a bios/grub prompt -nothing
5. I have to 4 second hold power button to shut down, remove disk from slot 2, start MSS, then after about 30 seconds, hit 'return' on the keyboard I have connected and the slot 1 disk starts to read. A few seconds later I am able to SSH to the MSS.

Im I missing somthing? Are my drives supposed to be a different format? Logical instead of physical? Do I need to load in SATA drivers first in order for a successful boot? If so how can I find out what drivers I need to get? I do not see my drive come up when I use lspci or when I use df.
