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.
