I've been looking for documentation to read up on HFS/HFS+ and hybrid a bit since I have to test an existing HFS-Format. Does anyone know of any test-software which is freely downloadable for the purpose of testing HFS-CD's? The most basic test would be of course to see if the CD is readable by a Mac but that wouldn't point out the individual errors present in the format generated or where exactly these errors are occuring. In case of UDF which is another fs format a UDF-verifier from Philips is freely downloadable from the internet and extremely useful in pointing out the individual errors present in an image i.e. at which points it fails to conform to the UDF-Standard. Does anyone happen to have/know of anything similar for HFS which one could use for this purpose ? As far as documentation is concerned I have the technical notes for HFS-Plus and chapter 2 of 'Inside Macintosh' for HFS. I couldn't come across any other literature of significance. I'd be grateful for any further links as well.
You might look at fsck_hfs, which is part of the Darwin open source project at Apple (see http://www.opensource.apple.com/). It is more oriented towards fixing problems rather than describing them, but it's a start. And of course the Darwin kernel contains the filesystem code for HFS and HFS Plus.
