so you now only have 2 disks in the machine, right? So you dont even want raid on it, correct?
1. If thats the case, you can just go with the suse installer all the way till the disk partitioning part. Then either take what it suggests or build your own configuration. Most likely youll want to format both disks to use reiserFS..
2. So, a full new install is what I think the suse installer calls it..
3. already answered in 1. (: The labeling of disks goes like this:
hda is the first disk (at the end of the first IDE cable, not sure how this goes with SATA or SCSI), hdb the second, hdc third and so on.. hda1 is the first partition of the first disk, hda2 the second, and so on.
