Why does the Western Digital Black Drive frequently change heads and make knocking noises? Why is only one side readable? Can the spare parts be restored, or not? Why can’t you see the scratched data or read it at all? To understand the specific reasons, check the black number of the Western Digital drive in this case. The road to recovery lies in understanding the issues on the platter.
In the past, especially around 2006–2009, models like WD800BB and WD800JD were known for their reliability. These drives typically had no major issues during data recovery, with minimal bad sectors and a high chance of successful recovery using 2-3 heads. The 1292 board was compatible with 1130 and 1335 boards, making the process smooth. However, as these drives aged, some began to show problems. The peak of failures occurred around 2008 due to mass production and widespread use by big manufacturers. This led to some customers complaining about the reliability of Western Digital drives, even though it was more about volume than quality.
From 2009 to 2010, data recovery became more complex. Previously, replacing 2-3 heads usually worked, but now, some drives would not fully seek after head replacement. The issue was that the drive might stop after just one head found its position. Solutions included:
A. Replacing the head again if the disk wasn't physically damaged.
B. Adjusting the head angle under a microscope to match the original.
C. Using UDMA virtual read technology to access data from one side.
D. Other methods that weren’t always effective.
By 2011, things were still manageable, but by 2012, the situation worsened. Drives that were 6–7 years old had reached the end of their typical lifespan (3–5 years). Many started failing due to circuit board damage, which often caused further harm when replaced. Long-term tapping could damage the servo area, particularly the 0th surface, making it unreadable.
When the 0th surface failed, even after replacing the head and board, the drive would still knock and fail to read. In some cases, the C drive could be recovered, but other partitions might not. Communication with the customer was key—many accepted partial recovery, while Others didn’t. Most customers who understood the limitations were willing to proceed.
One major cause of failure was overheating and oxidation of the PCB over time. If the drive wasn’t properly shut down, long periods of tapping could lead to serious damage. For example, a 5400 RPM drive tapped for an hour could accumulate over 324,000 revolutions, leading to irreversible damage. This often resulted in the 0th surface being completely unreadable or only partially accessible.
Another mystery is why the 0th surface couldn’t be read, while the 1st surface could. This remains unsolved and is still under investigation by physics experts.
The white-plated Western Digital drives, also known as "White Plates" or "Bai Fumei," had a much higher success rate. Their ROM versions started with 1XXX, allowing direct virtual mode reads without hot swapping. They were more compatible and less prone to physical damage, although they could still scratch the inner or outer rings. A key feature was the built-in self-test circuit that prevented long-term tapping, protecting the drive from further damage.
For multi-head drives, hot swapping required careful matching of head angles. Reading the 0th surface first helped identify partition information, and starting from the second partition avoided potential bad sectors on the C drive. Adjusting RAM settings improved the reading process and reduced noise.
When repairing modern Western Digital Black Drives, the steps include checking the PCB, replacing the head, cleaning burnt areas, replacing the motor, and handling unknown issues. While many problems can be resolved, some remain unexplained. Overall, the key to successful recovery lies in understanding the drive’s history, condition, and the right techniques used during the process.
