Sorry, have no experience with SFS, only the standard FFS and the one of OS3.9. I do know that I need to keep the first partition under 2 Gb, then install the OS3.9 and then to replace the filesystem by the one in SYS:L of the new installed OS3.9, using HDtoolbox of course. Once you do that you can use all the remaining extra space on your harddisc ... does this help
