Dumping Windoze

Hi, Is there an easy and safe method of removing windoze from a second hard disc and then rearranging the drives? Windows is on hda and SuSE 7.3 is on hdb and I would really like to dump windows completely and then have 7.3 as hda and the windows drive as a backup etc. as hdb. I have looked at Yast and haven't found anything that I can readily understand, I have only been a Linux user for 6 months, so any help would be greatly appreciated. Thanks Mike Ayers
