Steve, FaccII does not work on hard disks, true. There are some reasons for this. First, the new file system transfer's data directly to and from the user's address space. Having a program like FaccII for hard disks with the new file system would actually slow the system down by causing an extra copy to be done. The difference between this and the current file system implementation is that the current fs transfers 512 byte blocks while the new fs will transfer upto 128K at a time. Doing one sustained copy of 128K (one more than needed) would be a performance loser. Second, FaccII is geared for the stable configuration of 4 drives max. This assumption would no longer hold with hard disks requiring a substantial rework of the user interface. Anway, the bottom line is let's wait for the 1.3 version of kickstart to become stable before we consider any action.
