Hi, welcome to LQ and this forum.
It would be interesting to know how your WD IDE drive is seen as a block device.
So please launch the installer and once you've got the prompt (after the fake login as "root"), plug in a partitioned USB key, mount one of its partition as /mnt then issue following command:
lsblk -o MAJ:MIN,NAME,KNAME,FSTYPE,MODEL,SIZE,TYPE,MOUNTPOINT,STATE > /mnt/lsblk.txt
and attach lsblk.txt to your next post or just copy/paste it.
