So Suse tells you that you do not have ANY harddisks in your system? Or how exactly does your problem show itself?
It would help if you could wipe the partitions with a tool like partition magic, and set them to ext3 (or whatever you want to choose then).
Generally I would recommend to use a independent partition tool (or the linux one, if it has the treshhold of user-friendlyness that you need/like) to see what partition you have and if the HD is recognized correctly.
Your partitions might be hidden, although that is usually only done with recovery partitions on preinstalled systems.
