Hamilton, Ontario, Canada All Western Digital hard drives are also well-known for their firmware problems. Firmware of the drive is not located on the logic board as most people think.

Main part of firmware is stored on the platters in so-called Service Area. Service Area occupies the negative cylinders of the surface and contains a number of firmware modules. If one of the modules gets corrupted the hard drive fails to initialize correctly and stops working making the data inaccessible. In such case the drive usually spins up fine, it doesn't click but has one of the following symptoms: • it is not found in BIOS at all • identifies with its factory alias(for example WDC ROM MODEL-MAMMOTH---, WDC ROM MODEL-HAWK---), • shows up with wrong S/N (for example WDC-ROM SN# XYZ---) or capacity, • identifies fine but fails to read any data or boot up operating system giving I/O device errors whenever you try to access LBA sectors.

If you attempt to boot up from such drive or read any data from it you would get 'Primary Master Hard Disk Fail' or 'No operating system found' or 'USB Device malfunctioned' error or 'S.M.A.R.T. Capable But Command Failed' or 'Disk boot failure. Insert system disk and press enter', 'Hard drive not recognized', 'Drive Mount Failure' or some other hard drive boot error.

At the moment it is not possible to fix this kind of problem at home. It is quite a complicated job and requires use of specialized expensive equipment and deep knowledge of hard drive design and data recovery technology to repair the firmware. Luckily, it is not usually necessary to open the HDD in clean room and order donor drives, so chances of successful data retrieval are close to 100%. Another quite common symptom Western Digital drives experience is clicking/knocking/clunking/sweeping noise.
