I remember having that Eureka moment when I was a kid playing around with our Mac Classic. No modem so all you had to do was what was on your hard disk. And one of those things was Norton Utilities, which had a program called "Disk Editor". You could page through the sectors of the disk, one by one, and when there was some file-system-related data (HFS at the time) that it knew how to decode, you'd get a decoded view of it (WireShark-style) along with a pretty educational description of what it meant and was used for, which would also link file entries to the block where the file info was stored, etc. edit: since I couldn't find any online, I booted up the ol' PowerBook 540c and took some screenshots! https://kalleboo.com/retrotech/software/norton_utilities/norton_disk_editor-HFS_bootblocks.gif https://kalleboo.com/retrotech/software/norton_utilities/nor... https://kalleboo.com/retrotech/software/norton_utilities/norton_disk_editor-HFS_master_directory_block.gif https://kalleboo.com/retrotech/software/norton_utilities/nor... https://kalleboo.com/retrotech/software/norton_utilities/norton_disk_editor-HFS_extents_tree.gif https://kalleboo.com/retrotech/software/norton_utilities/nor... It also introduced me to trivia like how the names of developers were encoded into the file system, which felt like being let in on some secret https://kalleboo.com/retrotech/software/norton_utilities/norton_disk_editor-HFS_disk_type.gif https://kalleboo.com/retrotech/software/norton_utilities/nor...
