Hi, Sorry for the delay. I made an image using Disk Copy under OS 9. The image seems to contain a desktop database by default. Is there any means of creating images without a DTDB using DiskCopy so that I can compare ? Thanks!

How to use fsck_hfs on an unmounted medium?
by Pierre Duhem 14 Jun '04

14 Jun '04

Hello, I think I now understand the way to use fsck_hfs and I'm very pleased with it. I wish I would have known it in the past, when I first began to work on the HFS media. But back to the reason of my message: I use the df command to know which symbolic name to use when launching the utility. Is there a way to know wich symbolic name to use when the volume is not mounted? For instance, I have a HFS+ image, burned on a CD-ROM, which doesn't mount. The Disk Utility says that the node size is incorrect. I would like to check what fsck_hfs says indeed. However, since the unmounted CD-ROM is not listed by rge df command, which symbolic name should I use? Thanks in advance for any information. -- Best Regards Pierre Duhem Logiciels & Services Duhem, Paris (France) duhem(a)macdisk.com

Map node linkage
by Pierre Duhem 11 Jun '04

11 Jun '04

Hello, I'm still working on my HFS/HFS+ image formatter and I get a problem. I build a HFS image with about 41000 little files. The catalog mapping bitmap in the B-tree header overflows at about 6,500 files. The first independent node overflows at about 18,300 and the second at about 30,400 files. Therefore, I have following linkage: 0 (header) points to 0x0800 0x0800 points to 0x1770 0x1770 points to 0x26E0 However, when I run fsck_hfs on the CD-ROM I burned from this image, I get an error message: Invalid map node linkage 4, 9952 Btw, 9952 is 0x26E0 in decimal, which means that the program is not happy with my solution, in particular with the last node in the linked list. When looking at several volumes formatted and filled on a Macintosh (Mac OS X 1O.2, if it matters), I see that there is always a totally empty node (with nothing in it, even in the node header) pointed to by the last node where the bitmap was used. Should I also implement this? Thanks in advance for any clue. -- Best Regards Pierre Duhem Logiciels & Services Duhem, Paris (France) duhem(a)macdisk.com
