Full format will probably not wreck this partition but a completely different one. That's why it is so dangerous.
SFSFormat is only needed if you want to set special SFS options already at format time. You can always change them later by the supplied tools.
You should always use quick format for all harddrive parttions and with all tools. Full format does not make any sense on a harddrive, it just stresses the drive. Only if you want to sell the HDD and need to safely scratch each and every piece of private data, then a full format of the entire HDD makes sense.
