message: In the external link to MacTech's November 1985 article on HFS File Structure Explained one of the example catalog node (Cnode) names is "Letter to Birks, Druffey, & Co."  This seems to be a fairly coincidental name, as it very nearly matches the last names of Patrick Dirks and Bill Bruffy, who have been credited in this Wikipedia article with doing work on creating HFS.  Now if only someone (other than Dan Allen) can verify his book "On Macintosh Programming" () contains the reference.

replies: text: U.S. Patent 4945475 lists Bill M. Bruffey (note the subtle spelling difference) and Patrick W. Dirks as inventors of HFS.  The patent was granted July 31, 1990, filed November 21, 1989, and is a continuation of an application filed October 30, 1986.  It seems to contain a fairly technical description of a hierarchical filing system in general and not all of the specifics of the HFS found in Mac OS.  The assignee of the patent is Apple Computer, Inc.  According to Amazon.com, the inside flap of the book "Inside the JavaOS Operating System" () says that: "...Bill Bruffey of the MacOS group[...] is a great engineer who designed the Mac's innovative file system--the Hierarchical File System (HFS)." —204.42.20.6 03:32, 11 May 2006 (UTC)

Does Apple's Hierarchical File System let you write directly to tracks and sectors?
I found a lot of links to go somewhere else, but I looked all over this article for some kind of a clue as to how the file system works.   Instead of describing the Hierarchical File System in ways that may contrast it with the PC FAT system (which I have no idea how it works), there ought to be a description comparing it with the only file system I am familiar with, CBM DOS with its reliance on a BAM.   Somewhere there should be at least one reference to a Track or a Sector.   Where is it?   As it stands, the main article doesn't make any sense, and essentially tells me to go somewhere else to figure out what they are talking about.   I am not a Unix programmer, nor am I a PC user/programmer.   Dexter Nextnumber (talk) 22:19, 22 December 2009 (UTC)

thread_title:  No clumps mention 

message: When comparing various file format wiki pages, one will find that the HFS format suffers from an implicit bias. A section of “limitations” is present only on this wiki page detailing its shortcomings. While there are various wiki pages of tables neutrally compare the specs of various file formats, in the page HFS is unexplainably given a “limitations” section comparing it to other formats emphasizing it inferiority and proneness to problems. It is a given that all other file formats suffer from certain issues while their respective page curators do not allow the topic of limitations to be added as its is seen as irrelevant to the definition of terminology and description of their corresponding spec.  — Preceding unsigned comment added by 96.41.6.216 (talk) 13:18, 11 March 2021 (UTC)
