|10MB is a bit strange, as normally it would be 8 MB and would be called the lead in to the drive. It is where the meta data to the disc is stored and for some reason it is not being cleared during the formatting process. |
fdisk should have cleared the meta data as well as the OS installation disc
Now I know of some security programs that have created some meta data that becomes locked and a normal formatting will not erase it. Maybe this is what you have a problem with.
1) if it is a security program that was installed then as the owner you should have been aware of it.
2) Not being aware of it subjects it to a possible stolen computer in which case you had better hope it isn't the LoJack program because the police will be at your door the minute that computer goes on line!
With that in mind I am unable to assist you any further in your endeavor
