RK> It's only possible to trash if you are *very* lucky (unlucky), and are able to destroy enough information to make it unrecoverable. Otherwise CHKDSK /F:3 can bring most of an HPFS partition back to life. Heck, CHKDSK /F:3 even works after a FORMAT. To make HPFS unrecoverable, you not only have to remove the directories, but you also have to trash the bitmaps, trash the superblock, and eliminate all of the marker tags that identify individual HPFS structures. To do that, you'd also have to *find* them first (the only fixed part of HPFS is the superblock). I'd say that it was a lot more difficult to trash HPFS to the point of irrecoverability, given how easy it is with FAT (just zap two tables that reside in well-known places). RK> > You know exactly where on the disk each and every file is > under HPFS RK> If it was that easy, how come HPFS disc doctor programs are so few and far between ? In reality, the structure of HPFS is a darn sight more complex than FAT. Compare the code to for navigating a BTree (HPFS directories) to that for scanning an array (FAT directories).

That's the myth that the virus writers would like you to believe. It gives them self-worth.

RK> It was an worm, not a virus. And the plural of virus is viruses. Incidentally, what was said was not that it was impossible. What actually happened was that the companies responsible for sendmail and fingerd failed to patch security holes that they knew about, for the simple reason that they didn't think it economically viable for them to do so. RK> > Can't happen > here, just don't cut it. Someone, sooner than later, will > find a way and will do what can't be done. RK> Believe that if you like. But in two years of publically holding that same line (and I've said it enough times and in enough places that I expect that at least one virus writer would have felt challenged by it), viruses for OS/2 have spectaculary failed to appear. So I'm maintaining that line until proven wrong. OS/2 viruses would be far too cumbersome and far too visible to be viable. They'd not be able to do half as much damage as their DOS counterparts were they to exist anyway. And the evidence shows that they are far too difficult to write for the average virus writer, who obviously prefers the ease and lack of protection of DOS. > JdeBP < ___ X MegaMail 2.10 #0: --- Maximus/2 2.02* Origin: DoNoR/2,Woking UK (01483-725167) (2:440/4) SEEN-BY: 12/2442 620/243 624/50 632/348 640/820 690/660 711/409 410 413 430 SEEN-BY: 711/807 808 809 934 942 949 712/353 515 713/888 800/1 @PATH: 440/4 141/209 270/101 396/1 3615/50 229/2 12/2442 711/409 808 809 934 |
