I feel a little confusion
You say you partitioned
one harddrive, which is called hde (which is already strange, since this is supposed to be 3rd primary IDE controller, but this is certainly possible, especially if you have a SATA controller, too). On this drive, you created the partitions hde1, hde2 ,hde5 ,hde6 and I suppose hde3, which is the extended partition. You may say: "No, I didn't create an extended partition", but since Yast names them hde5&6, they are logical partitions.
But now my problem: hde is
one physical drive, how can hde3&4 be a SATA drive that you took out?
I guess your grub is as confused as I am. Try to boot from CD and see if this finds your root partition. After that, re-install grub with correct settings. Use
fdisk -l to get a list of your drives and partitions. Check if /etc/fstab matches these partitions and if Yast doesn't correct itself automatically, you may need to change the (hdx,z) parameter in /boot/grub/menu.lst.
