Hi Everyone,
this problem is because of firmware corruption of WD Hard disk drive that must be solve by Hard Repair Equipment like a PC3K ( a expensive hard repair hardware! ) but you can give your Western Digital hard disk to a HDD Data Recovery company to bring the information to you and do a hard repair for your precious Hard Disk.
i have that equipment and can do for you without any cost dear,
