1. copy SFS to sys:L (IIRC filesystems should be located in a partition that can be read by the rom so store your filesystems in the first 4GB of the HD in a FFS partition that can be accessed from KS3.1)
2. open HDToolbox. In the filesystems section, add the SFS located in sys:L
3. SFS will appear in the list of filesystems installed together with his version number.
3a. overtype the identifier by 0x53465300 (SFS) or 0x53465302 (SFS2, for partitions larger than 128GB). If you don't, the id will default to CFS (confused file system = stupid user sitting behind the keyboard).
4. Choose an empty partition and in the part where you set the block size, mask transfer, filesystems... choose SFS.
5. Save all the changes and exit hdtoolbox in a system friendly way. It will ask if you want to reboot, tell him you'll love it!
6. Once your machine has rebooted an alien partition will appear. You'll need to format it. You can format it from WB just like you would do with a normal partition.
7. enjoy. There are tools to perform a backup of the RDB, go make one backup as it would make save your precious data in the future.
