QuestionAccessing HDD drive Pin
_Flaviu14-Apr-20 9:32
_Flaviu14-Apr-20 9:32 
How is the way to open a HDD drive with _open function in such a way to read even the boot section of this drive ? Here is the code:

int hd_h = _open(device, O_BINARY | O_RDWR | O_EXCL);


device is provided with
"\\\\?\\E:"


This is the code from ntfs library GitHub - vitalif/ntfs-3g: Fork of git://ntfs-3g.git.sourceforge.net/gitroot/ntfs-3g/ntfs-3g with FIEMAP support patch[^]

Why I am asking that ? Even if _open return 3, further more, the reading of boot section has failed.

Function
ntfs_boot_sector_is_ntfs
say that my boot device is not NTFS:

if (! ntfs_boot_sector_is_ntfs(bs))
{
    errno = EINVAL;
    goto error_exit;
}


BOOL ntfs_boot_sector_is_ntfs(NTFS_BOOT_SECTOR* b)
{
	u32 i;
	BOOL ret = FALSE;
	ntfs_log_debug("Beginning bootsector check.\n");

	ntfs_log_debug("Checking OEMid, NTFS signature.\n");
	if (b->oem_id != const_cpu_to_le64(0x202020205346544eULL))	// "NTFS    "
	{
		ntfs_log_error("NTFS signature is missing.\n");  // <--- my code run by here
		goto not_ntfs;
	}
....


Of course, this debugging session ran as admin mode.
