That doesn't explain what you said about the MBR as being part of the 8mb....
part partitculer attention when my MBR is on 2 of my discs. My OS's are on those 2 discs where the mbr are at the end, too. the middle disc is my data
this was the best picture that I can get, but if you look hard enough, you can read it. this is from the powermax tool.
it will completely wipe (full format) the first 300 mb and the last 100mb of your hard drive, while quick formatting the rest of the hard drive to ensure that the MBR is completely erased without taking up all of your day doing it. now using your logic, why would they do that?
on previous versions of powermax you would have to pick the full format option (which took a looooonnnng time to do) if you wanted to completely wipe the MBR clean (it also completely wipe the hard drive too)

The unallocated space you are seeing at the end of Disk 1 and Disk 3 is exactly what I am trying to tell you. Disk 2 is part of Disk 1 hence it is treated the same logically and the unallocatted space you see in front of Disk2 is part of Disk1. BIOS is programmed to read the first sector of the active primary partition at cylinder 0, head 0 ,sector 1. Thus conclude that MBR always has to be at the begining of the partition which also includes your partition table which contain information about the location of other logical drives. Remember the MBR is only 512 bytes total! and no it's not part of that 8MB unallocated partition.
The low level format will completely destroy the data by rewriting over the existing data with new track and sector on the harddisk, why it write at the begining then skip to the end? I know it write to the begining to rid the MBR but skip the rest goes to the end that I don't know why I guess it's just a method use to quickly do the job! Note this does not rewrite the MBR! A high level format does this! High level format is what you do when you buy a new harddrive after the manufacture has already low level format it. The high level format creates the file structure such as the MBR and file allocation table. I rest my case.

powermax can't clean a boot sector virus or erase the mbr on it quick format option.
wow.....
what ever float your boat. you haven't rest anything. you just think that you are right
I guess you missed my point about powermax has a hybrid (that mean it mixed both methods together) high level, low level approach to wiping the hard drive clean, so that you won't be wasting your time (all day long) to wipe a boot sector virus on a 200 gig hard drive.
the partition table is with the mbr too. it is right before it (at the end of the a hard drive) and right after it (at the beginning of the hard drive)
let me rephrase this since you are trying to technolyze yourself into being right. some parts you know what you are talking about, some parts, you don't
the 8 unused portion of your hard drive is the boot sector. it included among other things a partition table, and a mbr. it also has the ability to control your computer if something is put in it (a boot virus, or MS locking your computer when they want to(they will put something in that partition tables since it is unused). that was something that they were doing 2-3 years ago, they are not reallly doing it now, unless you have a key that is on the blackballed key list. now, by locking your computer, I mean that you will lose function to 75% of your computer)
now I happen to call it the mbr, because it is included in the boot sector, I consider it the same thing. companies also do this to. for instance drive image 7 restore mbr.exe tool, it will fix a microsoft locked computer as it will rewrite the whole 7.8 mb part
now if you still feel like pressing on, just think that you have won.
I really don't care.
lately here on this forum, people think that it is more about sticking your chest out, instead of learning something new. I'm tired of all of the arguing. I am still stressed out from the last one when tyler1989 made the racial slur.
Going back to the very first post, the answer is this:

Up to 8MB of space is reserved just in case you want to upgrade to Dynamic Disk later.
Wikipedia's definition of MBR is this:
http://en.wikipedia.org/wiki/Master_boot_record
It is 512KB, and is located at cylinder 0, head 0, and sector 1 of the disk. (More info here.)
The MBR IS on each hard drive, but it's definitely not going to take up 8MB of space. I have never seen the MBR show up in Partition Magic nor any other kind of partitioning software either.
There's also tons of info at this website: http://www.geocities.com/thestarman3/asm/mbr/MBR_in_detail.htm

where is the mbr in relation to the partition table? Immediately right before the partition table . Now Anwser this. now where is that located? Guess what it sure in hell isn't in the formatted part of the hard disc. you must have missed it, when I rephrase what I had originally said
