I have a home-brew (ala MacSCSI) hard-disk drive on my mac and have been trying to run HFS on it. First I ran just the Finder 5.0. All this gave me was the same old file system with the new Finder 5.0 features. (Display small Icon,etc.) Then I downloaded a new System file that was meant to provide HFS1. Running this system with Finder 5.0 gave me some new Dialogue Boxes for Get/Put file dialogues. These dialogues have icons (either a micro-floppy or an HD20 icon) and apparently a mechanism for switching between folders (directories). The problem is that I can't seem to create REAL folders. Just the same old fake (non-hierarchical) folders of the old file system. I can't have files with the same name in two different folders. What gives? It seems like the new HFS is NOT getting loaded into memory as it must be with HD20. Where is the ram-based file system located?. It doesn't seem to be in the System file. What about the HD20 file? Does this have it? Perhaps there is some special Volume Information that must be initialized on the hard disk? If anybody out there has had any experience with this or has any suggestions/ comments, I would greatly appreciatte it. Frank Owen (..ihnp4!ttrdc!fjo)

Making HFS work with a hard disk has 3 major steps: 1) Put you hard disk driver into the new System. 2) Boot from the new System and Finder 5.0 3) Choose "Erase Disk" from the Finder to allow HFS to initalize the hard disk as a HFS volume. You got steps 1 and 2, but you missed step 3. Also, your Driver should respons to control calls #5 and #6, where #5 is a "Verify" command (just returning noErr is sufficient if you have no need for a verify) and #6 is a "Format" command (again, returning noErr is sufficient).

I think you also need the file "Hard Disk 20" on your boot volume. For MacSCSI users: The version 1 software from Fastime does not properlly set up dQDrvSize in the Drive Queue. This needs to go somewhere in np_drv.c (I think). This is a 16 bit field that contains the number of sectors on the volume.

What are the differences between the 5.0 and 4.1 finders?
