[opensuse] Trouble reformatting a HDD

I have bought a external HDD enclosure, and I have a 60 GB HDD in it. The problem is the hard drive currently in there is a old one that I used with winblows and SuSE 10.1. Now I am wanting to use this as a back up drive so I want to get rid of the current partitions and make a new one, I am thinking XFS would be good for this? Anyways I am trying to use the YaST2 partitioner, due to the fact I have no clue how to use fdisk, and when it tries to remove the current partitions (NTFS and reseirFS) YaST2 gives me the following error: "Error Failure occurred during following action: Deleting partition /dev/sdb7 System error code was: -1014" Any clue as to what is going wrong?
