Microsoft Denies Link Between Windows Update and SSD Data Corruption

Microsoft has denied any link between its recent Windows update and reports of SSD data corruption and hardware failure. According to users, some solid-state drives (SSDs) are experiencing data corruption and hardware failure after a recent patch. The issue is reportedly more prevalent in drives that are over 60% full.

The problem was first reported by a Japanese PC builder who noticed their NAND controllers would suddenly become undetectable while performing intensive write operations. After conducting tests, the user speculated that the issue could be caused by a memory leak due to an issue with the SSD's cache.

Microsoft has investigated the claims and found no correlation between its August 2025 KB5063878 update and the reported issues. The company worked with its partners who also failed to replicate the issue, declaring there was no increase in SSD failures or data corruption associated with the latest Windows update.
