[SOLVED] Install ArchLinux and Grub on external USB HD

Hi,
I'm trying to install Archlinux and Grub on an external USB HD.
I've unplugged my internal HD, plugged my USB HD, I went into the bios to change the boot sequence now my externel HD boot before the internal HD.
I've launched the install using the core CD iso.
I use cfdisk to create my partition on the USB drive. ( /dev/sda1 for boot, /dev/sda2 for swap, /dev/sda3 for /root ( ext4 ) and /dev/sda4 for /home ( ext4 ) )
The install finish find, I put Grub in /dev/sda.

Now when I boot on my external HD, Grub loads fine

here is my menu.lst

# (0) Arch Linux
title  Arch Linux
root   (hd0,0)
kernel /vmlinuz26 root=/dev/sda3 ro
initrd /kernel26.img

but I got an error :

Waiting 10 seconds for device /dev/sda3
ERROR: boot device didnt show up after 10 seconds...
/bin/sh: cant access tty; job control turned off.

[ramfs /]# _

I try to fix this problem, I search on the forum and found a post speaking about arch-scsi but when I type that at the begining of the install :

arch-scsi : command not found

Have you an idea to solve my problem ?
Thanks in advance! have a good day
( sorry for my bad english )

Did you add usb to your mkinitcpio hooks?

I highly recommend using uuids for removable devices. Also +1 on USB-hook.
