I just wanted to check if anyone knows if it is essential to have an empty B-Tree for the attribute and startup file in an HFS+ image. In case of HFS these weren't present in my image. In case of HFS+ I've increased the node size of the catalog to 4kB and included the other changes as discussed. Only thing I haven't done is to create a B-Tree for the attributes file and the start up file - in short I'm not writing anything into the image for these and have set the respective extents, sizes setc. to 0 in the Volume Header. Is this right or should these be present in the image as 'empty' B-Trees ???

I'm right now creating an empty volume with 0 contents but just the basic structures needed (the way I started off for HFS). The only problem is that I don't have any utilities to create sample HFS+ images which I can cross-check my image with.... Disk Copy on my iMac with MacOS 9 creates only HFS-Volumes by default and Norton Disk Doctor on my Mac recognizes the volume as MacOS Extended but doesn't really bring me any further (since my Mac is unable to mount the volume). There seems to be a hfsplus reader on Sourceforge since the end of last year but I need something like a sample hfsplus writer. Any idea if sth like this exists on the Mac or on other platforms. My Mac has just a CD-drive (no writer) and no floppy drive which make file transfer as cumbersome as it can get.
