And real programmers don't use Pascal. Also, stupidity must be punished (even if it's me who is stupid), and it _will_ be done. Always and repeatedly. You only learn the hard way. :-) > > Some fs-related articles here: > > http://www.mckusick.com/articles.html > > > This is one advantage of systems like FreeBSD. If the need > arises, you can do it yourself. Exactly, and you're not depending on buying expensive software that might not cover your particular problem case. The documentation of all the "inner elements" of FreeBSD are present, and you can learn (in worst case) everything yourself to solve the problem. As other skilled persons have estimated and experienced the need for professional tools, they've created them. Many of the free tools can cope with the expensive ones designed for proprietary platforms. The "default action" of UNIX ("if in doubt, do nothing and let the master decide") can save your data, whereas the habit of "repairing" things can make things worse (which includes automounting r/w, fiddling with the FS or other nonsense that destroys data). > > The docs that used to live in this directory now exist on the wiki: > > http://wiki.sleuthkit.org/ > > > It must be a disease. TSK had _good_ documentation locally installed. I don't really understand what's the idea behind moving it to a location that can only be accessed via Internet connection. Really, it's not _that_ much (hundreds of MB) that you couldn't leave it in the install... sad, just sad... Again, programs like portdowngrade help a lot. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
