Yeah I am not sure on this one either. There might be some tool out there, but I have never heard of it. Any particular reason you want to copy this?

yeah, What is one day i accedientally over ride my MBR and i don't how to reconfigure it at all. Un like if i did do that. My Uncle knows how to do it with a copy. The only thing i think he said but i'm not sure. I would have to get a hex editior. I think i would have to highlight the first 1024 cylinders or something like that. I do not know how to read hex notation.

So far there were three mods that could not answer that for me. I really don't care if your mod or not. I'm asking any of your guys out there. Do you know any programs that would copy my MBR for me?? Thanks.

You do know about http://www.google.com search, right ?

it's a search engine where you can type keywords into and get relative information back.

also, http://www.askjeeves.com

there you can ask questions and get directed to answers.

have you even tried ?

it's so easy to goto any board and post a question, then get frusterated
over the fact that noone has the correct or any answer for you.

when you are sitting in front of your computer,
you are in fact sitting at *the* largest library available to you.
providing you know how to use a search engine, ofcourse!

I'm not directing this in any bad way, just I would love to see someone
try a search engine once and a while to gain further knowledge about
any given subject in question.

We're all here to help oneanother ... but my comment would be try a search engine
if you are not getting any answers given here.

Look:

http://www.google.ca/search?hl=en&newwi ... gle+Search


Results: 12,700.   Search took 0.22 seconds


or .. perhaps this is something you could use;

http://web.ask.com/web?q=copying+Master ... rc=1&ste=0





I'll try being nicer, if you try being smarter!  ( j/k )

Q. How can I backup/restore my Master Boot Record?

A. A. The Windows NT Resource kit supplies a utility DISKSAVE.EXE which enables a binary image of the Master Boot Record (MBR) or Boot Sector to be saved.

DISKSAVE has to be run from DOS and so you will need to create a bootable DOS disk and copy DISKSAVE.EXE to the disk. To create a DOS bootable disk just use the command

C:\> format a: /s

from a DOS machine (do not do it from a Windows NT command session).

Once you boot with the disk you will have a number of options:

F2 - Backup the Master Boot Record - This function will prompt for a path and filename to save the MBR image to. The path and filename are limited to 64 characters. The resulting file will be a binary image of the sector and will be 512 bytes in size. The MBR is always located at Cylinder 0, Side 0, Sector 1 of the boot disk.

F3 - Restore Master Boot Record - This function will prompt for a path and filename for the previously save Master Boot Record file. The only error checking is for the file size (must be 512 bytes). Copying and incorrect file to the MBR will permanently destroy the partition table information. In addition, the machine will not boot without a valid MBR. The Path/filename is limited to 64 characters.

F4 - Backup the Boot Sector - This function will prompt for a path and filename to save the Boot Sector image to. The path and filename are limited to 64 characters. The resulting file will be a binary image of the sector and will be 512 bytes in size. The function opens the partition table, searches for an active partition, then jumps to the starting location of that partition. The sector at that location is then saved under the filename the user entered. There are no checks to determine if the sector is a valid boot sector.

F5 - Restore Boot Sector - This function will prompt for a path and filename for the previously save Boot Sector file. The only error checking is for the file size (must be 512 bytes). Copying and incorrect file to the Boot Sector will permanently destroy Boot Sector information. In addition, the machine will not boot without a valid Boot Sector. The Path/filename is limited to 64 characters.

F6 - Disable FT on the Boot Drive - This function may be useful when Windows NT will not boot from a mirrored system drive. The function looks for the bootable (marked active) partition. It then checks to see if the SystemType byte has the high bit set. Windows NT sets the high bit of the SystemType byte if the partition is a member of a Fault Tolerant set. Disabling this bit has the same effect as breaking the mirror. There is no provision for re-enabling the bit once it has be disabled.




Hey guys. I typed what they told me too. I tryed a couple of times. I was using MS-DOS 6.22 Operating System. At the command prompt. I typed this. C:\>format a: /s. I get a message that says it was invalid. What could be wrong?? How well do you guys know your way around DOS??

I believe its case sensitive and needs to be:

C:\> format a: /S

notice the /s is actually /S

Ok, well then type;

format c: -u

and when it asks, are you sure, hit 'Y'


that should at least fix *our* problems for a while!


just kidding, please don't do that ...

< grins evily >

looks like your a: drive is not recognized in DOS mode.

I don't understand what Unflux is trying to say about changeing directories. I really only know very least DOS commands. I have no clue on how to change a directory so my a: drive can regonize in DOS. Can someone explain that to me a little better? I don't understand what i would put in at the DOS command so my a: drive can recognize. Thanks.
