From PC Mag: The baffling Windows 11 update bug that corrupted SSDs now appears to be linked to storage drives running pre-release firmware.
Memory component supplier Phison says that "engineering preview firmware" appears to be the culprit after a PC building group in Taiwan figured it out.
Last month’s Windows 11 24H2 update, KB5063878, has been spooking the PC community due to anecdotal reports that it can cause an SSD to abruptly vanish from the PC or trigger the OS to freeze and crash. Strangely, though, both Phison and Microsoft failed to replicate the error.
A do-it-yourself PC building group in Taiwan was also flummoxed after encountering the problem on several of their own SSDs, including a Corsair Force Series MP600 SSD 2TB and a Silicon Power US70 SSD 2TB. But upon closer inspection, the group discovered all their affected SSDs “had been shipped with engineering firmware, not the finalized version,” the group wrote in a Facebook post.
On Monday, Phison confirmed that the affected SSDs, including the Corsair product, were “utilizing an engineering preview firmware, which is not the final firmware used. Phison also replicated the PCDIY! tests on-site with the same SSD models and the same stress tests (100GB/1TB writes) utilizing consumer-available SSDs and found no failures or crashes."
