Microsoft released KB5063878 a week ago (more about it here) as a part of Patch Tuesday updates. As usual, and seen previously, there are some issues encountered by the users, and this article talks about it. With this update, users are reporting issues where certain SSDs are being converted into RAW drives, causing the SSD to disappear or the partition to appear as “RAW.”, thereby making people think that Windows 11 update SSD failures are real. This means the storage may not show up in File Explorer (Windows) or even in the BIOS.

Windows 11 update SSD failures are limited to only specific regions and devices, affecting less than 0.5 % of the Windows user base
Upon Microsoft’s ongoing investigation and 3rd party investigations, it is safe to assume that most of the user base of Windows 11 is not affected by the KB5063878 SSD issue fisaco since the problem has a slight chance of arising only when SSD is more than 60 percent full, plus You are trying to write data on the drive in the large quantities.
The Windows 11 update SSD failures issue causes a clear pattern of problems. You may notice File Explorer stopping, freezing, or suddenly closing. At the same time, the system might not be able to read the drive’s health information (S.M.A.R.T.), and you may see I/O errors appear. In severe cases, the drive can disappear from your computer completely.
No, Phison controllers are unrelated to the problem
There are many reports that the Phison SSD controller is a common factor in all the SSD failures, but this seems incorrect. There are very few reports of the actual issue, and some other controllers, like InnoGrit and Maxio, are also having issues. You can see a potential list here.
It is fair enough to say that this issue is related to KB5063878, i.e. Windows update, and not a specific controller problem. But the good thing is. You are probably not affected by the Windows 11 update SSD failures issue –Windows has been the victim of sensational news for years, so you should not be surprised.
