try to recover using MTKFLash (Pure DOS version). also, if not mistaken, put ur "dead" liteon on the Secondary Master of IDE, heard that it would help recover ur drive -- even on some stubborn unrecoverabe badly flashed drive.
On most cases of bad-flashed drives, the BIOS will not be able to see the drive. that doesn't means the drive is dead, it merely means that it needs a proper firmware flash. the DOS MTKFlash should be able to resurrect such drive even when the drive is not detected by BIOS during bootup.
