    After that, I'm able to write to '\.\physicaldriveX' with no problem. I think the Win7 locks (unlike previous Windows releases) the physical device as long as there is any file system on the device to avoid consistency problems. You cannot directly access sectors of a drive which are owned by a mounted filesystem.
    See Microsoft's doc, CreateFile is the way to handle drives with no file system. What value is being passed as the access parameter to open_device ()?
    However, when I boot the virtual machine, VMWare Player says that it couldn't access the physical drive for writing. This seems to be a generally acknowledged problem in the VMWare community, as Windows Vista introduced a compelling new security feature that makes it impossible to write to a raw drive without obtaining exclusive access to it first.
    You cannot directly access sectors of a drive which are owned by a mounted filesystem. See Changes to the file system and to the storage stack to restrict direct disk access and direct volume access The documentation for FSCTL_DISMOUNT_VOLUME describes the following sequence for overwriting a filesystem: Open a volume. Lock the volume.
    I have come across only one possible solution, using the free virtual disk driver imdisk together with devio (remote drive access and acquisition). As imdisk is a kernel driver, it might be able to write to the partition. Unfortunately, as devio works in user-mode, I am not too sure whether this approach will work for you.
    The first hexadecimal digit shows the start and thsecond shows the length of partition. That means all the device objects representing disks and partitions are chained in driver object of disk class driver (i.e. disk.sys ). Now to enumerate the device objects created, you first need to have access to the driver object of disk class driver.
