The PC world never seems to rest—if anything, it churns out surprises with alarming frequency. Just when you think things couldn’t get more complicated, a Windows 11 update comes along that could potentially break your SSD, corrupt your critical data, and turn simple tasks like installing a game into a nightmare. Today, I’ll break down exactly what’s happening with the latest Windows updates, explain how to check if you’re affected, and guide you step-by-step through safeguarding your files before disaster strikes.
This guide isn’t just a dry technical breakdown—I’ll add insights, human experiences, and clarifications wherever it helps. Let’s do this together, making sure no step goes unexplained and that you walk away empowered, not overwhelmed.

1. Setting the Stage: What’s the Trouble with Windows 11 Updates?
Modern computing seems like a game of chance at times. Windows updates are supposed to make things better, but sometimes they do just the opposite. Recently, users started reporting issues with their solid-state drives (SSDs) after installing updates KB5063878 and KB5062660 for Windows 11. Those not in the preview (or beta) program usually see KB5063878, while preview users are hit with KB5062660.
So, what’s really going on? These updates seem to be causing serious issues with certain NVMe SSDs, especially those using Phison controllers. You might not notice any problems right away, but when you transfer large chunks of data—think installing a new game or copying important files—the affected drive can disappear from Windows entirely. Some users have seen their systems crash, experience blue screens, or worse, face data corruption.
Let’s move forward with a closer look at how this bug shows up!
2. Symptoms and Risks: What Happens When Your Drive Vanishes?
Imagine you’re downloading a massive new game or moving a pile of work documents. Suddenly, your computer crashes, your SSD vanishes from Windows, and you’re left staring at a blue screen. It’s not just annoying—it can lead to permanent data loss.
Here’s what’s currently known about this bug:
- The issue mainly rears its head when writing around 50GB or more of data. That could be any hefty file install, update, or transfer.
- The effect worsens if your SSD is over 60% full.
- Sometimes, restarting your system makes the drive visible again. But in a few scary cases, the drive does not reappear or data is lost forever.
- These problems started showing up in the last few days and have been confirmed by Phison, though Microsoft hasn’t formally recognized them as of now.
If you’re running a Windows machine and regularly install games, transfer videos, or work with large datasets, you need to proceed with caution.
3. Which SSDs Are Actually At Risk?
Let’s take a pause and sort out who’s most vulnerable. The root cause lies in a kernel-level Windows update affecting certain SSD controllers—especially the Phison PS5012-E12. This controller is popular and found across many brands, but other controllers are implicated as well.
Before you worry, here’s a rundown (with a little extra info):
SSDs Confirmed As Affected
- Western Digital Blue (500GB, 2TB): Recovered after reboot.
- Western Digital Red SA 500 (1TB): Recovered after reboot.
- Western Digital Blue SA5701 (1TB): Recovered after reboot.
- WD Blue SA5102 (2TB): Did NOT recover after reboot in one test—a serious risk.
- Corsair MP510 (960GB), Corsair Force MP600 (2TB): Recovered after reboot; all sizes potentially affected due to shared controller.
- SK hynix Platinum P41 NVMe: Recovered after reboot.
- Crucial P3 Plus NVMe, AData Legend 800 (2TB), HP FX7000 (2TB), XPG SX8200 Pro (2TB): Most recovered after reboot, but risk is still present.
- SanDisk Extreme Pro M.2, ADATA SP580: Scattered user reports—pay close attention if you own these.
- Kioxia Xeria Plus G4, Kioxia M.2 SSDs: Mainly found in enterprise setups; servers running these may face massive issues.
- SSDs using InnoGrit or Maxio controllers: Newer reports suggest these might also be hit, though Phison remains the main culprit.
Controllers at-risk:
- Phison PS5012-E12 (Wide market share!)
- InnoGrit
- Maxio
A moment here: if your drive isn’t on this list, don’t exhale just yet. This is early data—more drives may be affected as testing continues!
4. Drives Currently Tested as Unaffected
Let’s relieve some anxiety for a moment. Testing by sites like Tom’s Hardware and WCCFTech shows some SSDs aren’t struck by this Windows bug, even under heavy loads.
SSDs That Did NOT Fail in Recent Tests
- Samsung 990 Pro, 980 Pro, 870 EVO
- Western Digital Black SN7100
- WD Blue SA510 (1TB) (oddly, 2TB version is affected!)
- Seagate FireCuda 530 (1TB and 2TB)
- Solid GM P44 Pro
- Crucial T700
- SanDisk SSD 240GB (A rare old model!)
Keep in mind, results can change as updates and conditions evolve. If your drive is not on the “affected” list, you’re probably fine, but extra caution never hurts.
5. Real-World Headaches: How This Bug Confuses Users
If you’re here, you might have experienced some frustrating moments lately. Here’s a scenario:
You try to install a new AAA game from Steam. The installer chugs along, hits that ~50GB mark, and—bam!—your PC blue screens. You reboot, and sometimes the SSD reappears. Other folks have been chasing imaginary RAM problems, checking CPU and overclocking settings, suspecting Expo or XMP memory profiles. But the culprit? This update.
Take comfort—you’re not alone. Countless users and tech forums are lighting up with stories just like this. Let’s make sure you know how to fix it before it can do real harm.
6. How to Check If Your SSD Is Affected
It’s time for some detective work—let’s walk through each step carefully.
Step 1: Identify Your SSD
- Open the Device Manager (Press Windows + X, then choose “Device Manager”).
- Expand “Disk drives” and note the model name/number of your SSD.
- Look up your drive’s controller (manufacturer and model)—refer to the specs on your vendor’s website if needed.
Step 2: Check for Affected Windows Updates
- Go to Settings > Windows Update > Update history.
- Scroll down to “Quality updates.”
- Look for KB5063878 or KB5062660.
- KB5063878 (standard release)
- KB5062660 (Windows Insider/preview builds)
So far, so good? If you find either update installed, and have a listed controller/SSD, you’re at elevated risk.
7. Recommended Immediate Actions: Undo the Update!
Alright, let’s move to the critical part—uninstalling the updates before catastrophe.
Step-by-Step: How to Roll Back the Errant Update
Before you start, make sure you back up your data. Use an external drive or cloud solution just in case.
- Go to Settings > Windows Update > Update history.
- Click “Uninstall updates.”
- Find update KB5063878 or KB5062660 in the list.
- Click Uninstall.
- Restart your computer.
This process removes the problematic update. Most users with affected SSDs find their drives return to normal operation after this fix. If you continue having trouble, consider consulting your SSD vendor’s support site for firmware updates or additional guidance.
Extra tip: Consider disabling automatic updates temporarily, to avoid the same update sneaking back in.
Go to Settings > Windows Update > Advanced options > Pause updates.
8. Why Is This Happening? Exploring the Cause
For those who want a deeper technical insight, here’s what’s likely occurring:
The Windows update tinkers with the kernel-level storage subsystem, interacting with certain SSD controllers in ways that break compatibility. Under heavy write loads (large installs, big file transfers), the drive’s firmware and system kernel can “desynchronize,” causing the drive to disappear completely, sometimes without leaving a trace.
While most drives come back after a forced reboot, some do not. In rare, worst-case scenarios, you could lose data (or worse, the drive’s partition table). Remember, Phison isn’t the only controller in the game—others like InnoGrit and Maxio are now showing similar problems.
9. Pro Tips for Staying Safe During Update Turmoil
Let’s add some practical, actionable advice for keeping your PC and data healthy:
Before making system changes, always create a backup.
Monitor tech news sites for update advisories—Tom’s Hardware, WCCFTech, etc.
Prefer manual Windows updates over automatic, so you can review potential issues before installing.
Frequently check SSD vendor websites for firmware patches.
So far, we’ve navigated treacherous waters together. The next step: ongoing vigilance and troubleshooting strategies!
