<style> BODY { font-family:Arial, Helvetica, sans-serif;font-size:12px; }</style>Thanks, Frank. That's just what I was looking for.<br>
<br>
The CD is mounted a long distance away from the the CPU board and the IDE cable doesn't reach. No power cable either, so the floppy solution is probably easier.<br>
<br>
I have been experimenting with WDe, a nice GPL disk editor that runs on DOS. It will save a sector to a file, but for some reason it won't restore from a file to a sector for me. The author seems very interested in getting to the bottom of it and I'm in no hurry so I'm happy to work with him.<br>
<br>
Perhaps I'm being 'way too cautious, but I want to be able to undo any changes I make (even restoring the virus) if necessary.<br>
<br>
I will definitely download the CD and floppy images.<br>

<br>
LDE is a GPL'd lookalike to the old Norton Disk Editor in the same way that Midnight Commander looks like Norton Commander.<br>
<br>
Lots of other neat stuff on the SystemRescueCD disk, too.<br>
<br>
Can you only boot from a floppy? If so, it is possible to fit a minimal Linux with LDE on a floppy. Luckily someone else has done it for you!<br>

<br>
It's a two-disk solution, the first has the minimal boot disk, the second has lde (included in the hdd_fix.img).<br>
<br>
You'll need to write the two disk images to floppies, write back if you need help.<br>
<br>
The disk images on that page make for a very useful toolkit...<br>

Subject: [NBLUG/talk] Looking for a bootable disk editor<br>
To: talk@nblug.org<br>

<pre>I'm not a sysadmin of any denomination and have no business on this list <br>
but I've been lurking ever since an installfest a few years ago.<br>
<br>
I work in a semiconductor fab and have engineering responsibility for an <br>
instrument with a built-in and not upgradeable, hardwarewise, PC <br>
controller. Someone on the previous watch had managed to migrate from <br>
Windows 3.11 to Windows 98. I sent the instrument out for repair about 6 <br>
months ago and it came back with 3.11 again. Some calibration function <br>
didn't work under '98. But, it now has the NYB boot-sector virus. By<br>
all <br>
accounts, this beastie is pretty benign, seeking mainly to replicate and <br>
spread itself.
However, the application is crashing regularly and it <br>
seems the first thing to do is get rid of the virus.<br>
<br>
I did a web search and some sources suggest I just run FDISK /MBR to <br>
rewrite the master boot record. Another source says the virus/worm will <br>
have copied absolute sector 1 to sector 17. It's not clear whether the <br>
bug will have overwritten the partition table at the end of sector 1. If <br>
it has, restoring the MBR only will render the PC unbootable.<br>
<br>
So, I'm looking for a bootable disk editor, preferably free, that will <br>
allow me to inspect sectors 1 and 17 and copy portions of one to the <br>
other if need be. I thought I'd find an open-source utility to do that, <br>
but no joy. I downloaded the trial version of Acronis Disk Director <br>
Suite 10.0 which contains 'way more than I want but it appears that the <br>
disk editor component is read-only.<br>
<br>
Any ideas? I can boot from a floppy or CD.<br>
<br>
BTW, the guy
who gave me the virus left the company he was working for <br>
shortly afterward.<br>
<br>
Thanks,<br>
