Western Digital denied that some of its SanDisk Pro and other external SSD fail because of a hardware problem, as stated by the head of Attingo, a data recovery company, last week. In a statement released to PetaPixel, Western Digital claimed that it ensures product quality through a thorough design for manufacturing process, adherence to IPC standards for PCB design and assembly, use of high-quality solder paste, and extensive pre-shipment testing.
"The recent statements suggest that hardware components may have been responsible for the firmware issue that impacted certain SanDisk Extreme Pro 1TB, 2TB, and 4TB, SanDisk Extreme 4TB, and WD My Passport SSD 4TB portable SSDs earlier this year," a statement by Western Digital reads. "While we are working to gather more information, at this time we do not believe hardware issues played a role in the product concerns that we successfully addressed with the firmware update."
Markus Häfele, Managing Director of Attingo, a data recovery company with over 25 years of data recovery experience, told an Austrian website that his company encounters failed SanDisk Extreme, SanDisk Extreme Pro, and WD My Passport SSD. Western Digital is even facing a class action lawsuit because of these failures.
Häfele noted multiple hardware issues with these drives, including mismatches between the size of the components and the circuit boards they are attached to. This mismatch leads to unstable connections and overheating, which in turn makes the SSDs more susceptible to damage. Furthermore, the solder used in these devices tends to form bubbles, compromising its integrity and leading to easy breakage. The root cause of actual failures — whether it is the low-quality solder, the inappropriately sized components, or a combination of both — remains unclear, but the drives fail because their hardware fails.

Specialists from Attingo observed that recent versions of these SSDs have been altered by adding extra epoxy resin, presumably to better secure the ill-fitting components. This alteration suggests that their producer might be aware of these hardware flaws and tried to fix it. Yet, despite these changes, the newer models of the SSDs are still prone to failures, resulting in a steady stream of customers seeking data recovery services from companies like Attingo.
Nonetheless, Western Digital continues to insist that some of its SSDs failed because of firmware problems, which have been fixed. It is unclear why newer version of these drives reportedly continue to fail, however.
