Hi,

i hope i will get an answer here after done 4 forums. I am looking for how to write and read at specifical address in a hard disk under Windows 7. I mean by specifical address, in a sole physical sector https://en.wikipedia.org/wiki/Disk_sector and without taking care of any file or file system. I am using c++. So i specify again i am looking for a fonction in c++ who asks a physical sector address and go to search all bit who are in this sole sector, this fonction should not have relation with any file or file system.

you open the disk device using a special file name...

https://support.microsoft.com/en-us/hel ... nder-win32

open with CreateFile

calculate offset into file using sector size and off you go....

cheers

(the above link is broken intentionally - COPY the link and remove space between https: and // cause the forum does not like the address with .aspx ending)


Wouldn't it have been easier just to wrap it in a BBcode 'url' tag instead?

Lisp programmers tend to seem very odd to outsiders, just like anyone else who has had a religious experience they can't quite explain to others.
