We have had no luck with the Linux version and are currently sticking with Windows
Dave Graham provided a {{:hardware:dg_email_2010_05_11.rtf|current version of the Linux implementation on 2010 May 11}}. The files were downloaded and placed in a directory on a Linux PC. An empty USB-mounted HDD was used and partitions created to match the first two as described in the READ.ME file provided by Dave. This was done using ''fdisk''. The first partition was tagged as bootable.
Then ext3 filesystems were installed on each partition using ''mkfs.ext3''.
The image of the first partition was then copied to the disk:\\
''dd if=dd_sda1 /dev/sdc1''
The file ''boot_sector'' was copied to the master boot record:\\
''sudo dd if=boot_sector of=/dev/sdc bs=512 count=1''
Then the first partition was mounted at /mnt/tmp\\
''sudo mkdir /mnt/tmp''\\
''sudo mount /dev/sdc1 /mnt/tmp''\\
Then find out the disk ID:\\
''ls -l /dev/disk/by-id | grep sdc''\\
Then edit the fstab file in the mounted partition so that the / partition has the ID of /dev/sdc1 and /usr2 is at /dev/sdc2, /data at /dev/sdc3. /etc/fstab then looks like this:\\
/dev/disk/by-id/usb-WDC_WD75_00AACS-00D6B0_DCA425712418-0:0-part1 / ext3 acl,user_xattr 1 1
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
/dev/disk/by-id/usb-WDC_WD75_00AACS-00D6B0_DCA425712418-0:0-part2 /usr2 ext3 acl,user_xattr 1 2
/dev/disk/by-id/usb-WDC_WD75_00AACS-00D6B0_DCA425712418-0:0-part3 /data ext3 acl,user_xattr 1 2
also edit /mnt/tmp/boot/grub/menu.lst and change the disk ID.
The disk can now be booted from.
