My goal is to manipulate the boot-sector in my flashdrive (volume E:) I am using XP.
I am able to read the boot-sector
FILE *fp_read = fopen("\\\\.\\E:", "rb");
/* Able to proceed to read boot sector */
however i am not able to open the file to write using fopen in 'wb' mode.
FILE *fp_read = fopen("\\\\.\\E:", "wb");
/* Unable to proceed due to Failed to open file to write.:Permission Denied */
The flash-drive is not in use at the moment of execution.
Hex-editors are able to manipulated boot sector etc, i believe it possible to do so in c.
Any suggestion or insight to overcome the access problem so as to be able to write?
