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

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. That would ba a 100% secure way to wipe a disk befor giving it away Alain - This SF.net email is sponsored by: Microsoft Defy all challenges.

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.

It's my very first post to the list, so greetings for all. I've finished the 2.3 version of Destroy. It's a file wiper program, that overwrites your files several times, and deletes them. Therefore, nobody will be able to undelete your files. Yes, every file wipers can do that, but mine offers several additional options. (Run with /? to list them.) The destroyable files can be specified by - filemask (of course) - attributes - size - time By default, Destroy overwrites your files only once with 0 characters, but in V2.3, it's possible to overwrite files more times, using different characters. Run the program with /?D to list the several destroy levels. It's even possible to set the program to don't overwrite your files, just delete them. This option is suitable for users who would only like to use the program's filtering options. (For example, I'll use that to get rid of my very old and irrelevant IRC logs.) Of course, the program is under GNU GPLv3 license. At the moment, the software is only accessible from a temporarily-created GogglePages website, since the server of my main website is down at the moment. :( http://megabrutal.googlepages.com/home 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, if you take a look at it.
