Western Digital WD4001ABYS Data Recovery Information
Western Digital drives fail and the WD4001ABYS is no exception to this.
   
The hard drive makes a high pitch noise, then starts to clicks, it seems to spin up ok, the clicking then stops afer 2 minutes. The hard disk also rattles when I shake it. The model number is: Western Digital(model WD4001ABYS)

When it comes to data recovery one of the most common problems Western Digital hard disks experience is burnt board (PCB).Western Digital manufactures a large portion of the world's hard disk drives. In recent years the company has broken ground in the storage industry with a number of innovations. In 2001, a series of ATA hard disk drives (Special Edition) with an 8MB cache buffer were released at a time when most hard drives ran with only a maximum 2MB of buffer. Then, in 2003, they launched the world's first 10,000RPM Serial ATA hard disk drive, The Raptor, a 36 GB unit with an access time of less than 6ms - followed soon after by a quieter 74GB version. Western Digital drives are vulnerable to overheating. Bad power supply unit's combined with a power surge is usually enough to damage micro chips on the electronics PCB and make the data inaccessible.
WD4001ABYS. If your drive suffers from an electronic failure then we can recover the data for you. In our data recovery lab we use specialised hardware systems to modify a new PCB electronic board and then use specialised software to rewite corrrect firmware modules to the hard drive. This Western Digital fix helps us recover a large precentage of these electronic damaged drives.Western Digital spins up fine. I am trying to recover data from a hard drive that seems to have gone bad. I get a clicking noise and it will not show up in the bios and if I use a USB adapter on it I just get an error message saying that the hardware did not install properly and will not work correctly.
The arm in the hard drive just keeps resetting and that it what the click is. Its a continuous click, (every 2 seconds or so).

Western Digital drives have a tendency to sustain damage to the hard drive's firmware zone thus blocking access to the data on the hard disk. Typically, when the system is booting up, it will hang for a few seconds while the BIOS tries to find the volume. Even though the hard disk may or may not be recognised correctly (if at all) the drive's performance will slow dramatically before it the hard disk fails altogether, other failures include:
- It is not found in BIOS when you boot your computer.
- Identifies the hard drive as its factory alias (for example WDC ROM MODEL-HAWK)
- Shows up with wrong S/N (for example WDC-ROM SN# 254) 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 the sectors on the hard drive.
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 "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.
The Western Digital drive can spin up and the head starts clicking right from the beginning with a regular clicking sound . WD4001ABYS">More times than not this a sign of bad heads, if this is the case it is very important to perform accurate diagnostics and eliminate a chance of possible firmware corruption or PCB failure that sometimes could also cause clicking.
My computer is setup with a Raid-1 array. One of the drives dropped off the Raid array. I went into the raid utility to rebuild it. I chose the rebuild button and nothing happened. When I looked at the drives in the case, the sata infomation cable slipped off the drive. I turned off the computer, re-attached the cable and rebooted. The computer sees the drives as it's booting up, but, just goes past the raid utility. It won't enter it. Then when it gets to Windows, it says, "Disk Boot Failure. Please insert a system disk.."

WD4001ABYSHeads are normally parked on the parking ramp outside of the platters, but sometimes after a fall or abnormal termination they fail to return to their regular parking position and are left on the surface. Immediately after the motor stops spinning they stick to the ideally smooth surface and it becomes impossible to free them without proper tools and experience. Don't attempt to open the drive by yourself - you will damage the platters and this will make your data unrecoverable.
The last typical Western Digital hard drive issue applies also to all other hard drive makes and models, the problem is called bad sectors. After some period of time the platters were the data is located starts to degrade and bad sectors appear.
Whenever the hard drive attempts to read bad sectors it could start freezing, scratching, ticking and sometimes loud clicking. This leads to further damage to the surface and causes more data loss. As soon as you start experiencing such symptoms while reading important files, stop the drive immediately and consider sending it to a data recovery company like ourselves for a free diagnostic. Any further attempts to read the Western Digital drive would just add up to the problems and make more data unrecoverable. In our Data Recovery Lab we use expensive imaging tools that are capable of force reading bad sectors from Western Digital Hard Disks. This is usually the only way to effectively retrieve data from these Drives.
If you experience any of the symptoms described above with your Western Digital WD4001ABYS please call us on +44 (0) 2890 961976. If you hear your Western Digital WD4001ABYS hhard drive making some other unusual noises please call us on +44 (0) 2890 961976.
