10.3: Use Secure Empty Trash to reclaim hard disk space
Authored by: jaydisc on Dec 15, '03 05:43:22PM

I think all of these assumptions are incorrect. When you delete invisible items, you trash can does not show the full icon, and Empty Trash/Empty Secure Trash commands are unavailable. I think either packages or invisible items have been deleted before you attmempted this exercise, and therefore, it must write seven passes of random data over EACH piece of the package and/or each invisible file.

10.3: Use Secure Empty Trash to reclaim hard disk space
Authored by: jamiefiedler on Dec 15, '03 05:48:12PM

i'm going to guess maybe secure delete rebuilds directory & file system related database files & rewrites over their old sectors as well as the actual deleted files, to remove any file system links that may contain filenames, sizes, creation/modification dates, finder comments, etc. this rebuild may somehow save/reclaim space when being performed...

this is all just guessing...i have no technical information to back this up whatsoever!

Well, your theory is more likely than one proposed above, that secure delete trashes cache files, since secure delete just writes over and deletes things that are in the Trash, and cache files that aren't in the Trash, are just that--they're not in the Trash, and so they stay put until you drag them there, or OS X deletes them, so emptying the Trash in any fashion shouldn't delete cache files that aren't in the Trash.
