Re: [Freedos-user] Announce: DESTROY version 2.3 file wiper for DOS

Just a reminder: A much more simple wipe-before-delete can be acconplished with my version of XDEL, which is compatible with DrDOS's. I'd like to ask your opinion about the software. Do you think it's useful? Should it be included in the next FreeDOS distribution, or it isn't worth that much? :) Thanks, I would like very much to have a progrmam like that that wipes a little more: 1) all unused area of the disk 2) the whole disk, something to use after a) booting freedos b) running format.

Well, then I have to do some advertising too :-) You can as well use my little tool called DESTROY - http://mateusz.viste.free.fr/dos/en/destroy.htm I'd like to ask your opinion about the software. Do you think it's useful? Of course it's useful! By the way, bigger is the choice of tools, better will be FreeDOS.

FreeDOS is an operating system, not a massive destructor :-) You can use for example DBAN (Darik's Boot And Nuke), which is an open-source bootable CD giving many usefull option to unrecoverably erase hard drives. http://dban.sourceforge.net I use it each time I am selling an used computer, and it do the work very nicely.

Re: [Freedos-user] Announce: DESTROY version 2.3 file wiper for DOS
Of course, a _secure_ file wiper needs to do more than just write 0's to the disk. With the right equipment, that's fairly easy to recover the data. A more secure file wiper writes patterns, including random data, to each block to make the disk unrecoverable. DBAN does a very good job of this, and so do others (GNU shred from GNU coreutils is very nice.) -jh On 9/24/07, Eric Auer [EMAIL PROTECTED] wrote: Hi Alain, I think in particular a slack space wiper would be nice.

[Freedos-user] Possibility of floppy installer for FreeDOS?
Hi all, I would like to suggest, if not already available, that the base package of FreeDOS be made available as a set of floppy disc images as well as just a CD. I for one have an old machine I'm messing about with which has no CD drive installed (though possibly could do if it has the right interface (IDE?)) I'd like` to knowq if I could possibly find one, or a suitable alternative to an actual installed version of FreeDOS (Baldur maybe?) I've posted a similar suggestion on the FAQ by the way.
