Tachi- said:MrChom said:Actually hard drives are divided into sectors, it's part of the fundamental nature of the File Access Table technology. If your hard drive wasn't in sectors then the likelihood is that every time you wanted a file your PC would have to read the whole drive to find it (like the old tape drives).
Incidentally it IS possible to nigh on brick a modern PC with an old DOS boot sector virus. Many of these viruses would simply put their code in the boot sector, and have a pointer to the end of the drive to get the real boot code...problem is that they were written with DOS in mind, and Windows XP writes data differently. Hence how a virus from the 80s managed to cripple my PC a while back. Easy enough to fix by formatting, but still a pain.
Anything talking about the zero sector of the disc is just fiddling with boot code, something Windows nowadays tries to prevent, and something that is USUALLY only possible by having a floppy disc/CD with a virus on in the machine at boot time. Like I said, not fatal....just one windows reinstall from a fix.
Chom, Have you completed the computer A+ course to learn that much about sectors?
Thinking about it i might write a batchfile to counteract the "virus" and send it round.
It states norton internet security is looking into ways to fix the virus. but a batch file could stop the virus from affecting the harddrive in the first place.
Haha, no, sadly my experience with the sectors/heads of a drive comes from my days with Windows 3.1 (watching the hard drive defrag in DOS was a great source of excitement, drives were slow enough you could see data being shifted around), a bad experience with the aforementioned "FORM" virus that was on a floppy disc from the 80s, and my Computing A-Level. Never took A+ cert as the guy teaching the courses said that with my background knowledge I should be able to get my head round the concepts anyway.
And, yes, common sense is the best solution to the alleged "postcard" virus. Like I said, the stuff quoted at the top of the thread is JUST close enough to reality to be believable but describes a kind of virus that has been going round since the early 90s. Keep your email client up to date, Windows patched, a virus scanner installed/updated, and always scan any executable you download from an un-trusted source. It's simple things, people, no need to counteract them, virus scanners have been dealing with this stuff for years.
For those of you without a virus scanner: http://free.avg.com/
It's not brilliant, it won't get 100% of everything, but it is free, it does update itself, and is fairly easy to manage. Like has been said, common sense deals with 95%+ of these problems.
