If your Windows 11 update is failing with error 0x800f081f for KB5064081 or KB5065426, the first thing to do is run the Windows Update Troubleshooter. Go to Settings → System → Troubleshoot → Other troubleshooters, then click Run next to Windows Update. You should also check for corrupted system files by opening Command Prompt as admin and running these commands one by one:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Restart your PC and try the update again. If it still doesn’t work, you can manually download the update from the Microsoft Update Catalog
or reset the Windows Update components by stopping update services, renaming the SoftwareDistribution and Catroot2 folders, and restarting the services.
Another common cause is missing .NET Framework 3.5, which you can enable by running optionalfeatures.exe and checking the box for it. If all else fails, use the Windows 11 Installation Assistant from Microsoft’s website to repair any missing files and apply the updates. Following these steps usually fixes the 0x800f081f error without having to reinstall Windows.
Your 4TB WD My Passport looks like it’s got a hardware or firmware problem since it powers on but won’t show up on any computer or in Disk Management. That usually means something like a bad controller board, firmware issue, or mechanical failure. Keep powering it on, and you could make it worse. Software recovery won’t help since the drive isn’t being recognized, so you’ll need professional data recovery. Here in Dallas, places like DriveSavers, SalvageData, and Gillware can get your data back and transfer it to another drive. If it’s still under warranty, WD might replace it, but they usually won’t recover your files.
Jace, you’re right. With RAID 5, two failed drives usually mean the array can’t rebuild on its own, but recovery can sometimes work if the failed drives are still readable or can be imaged. Software like R-Studio, UFS Explorer, ReclaiMe, or Stellar RAID Data Recovery can try a virtual rebuild without overwriting what’s left. Forcing a rebuild from the RAID controller is risky and can destroy the remaining data.
Have you checked whether the failed drives are still readable or if you can make full disk images of them before trying recovery?
I don’t remember exactly what @Ezra used but yeah I can confirm repair tools are kinda the way to go if vlc fails. I recovered my hiking videos the same way. Took like 5–10 mins.
@Ezra do you remember the name of the one you used? I keep finding shady sites and don’t wanna make things worse.
Ngl easiest way I found was using repair software. Most of the free ones online are junk but I had one that actually worked on my drone footage. It rebuilds the damaged parts automatically.
@Silas true. I fixed my niece’s birthday clip using that method. but it’s tricky if you don’t have another video shot from the same camera/phone.
In that case, it’s probably the header of the mp4 that’s broken. players can’t read how the video or audio is structured. There are tools out there that rebuild headers using a “sample” healthy file from same device.
Yeah sadly I tried my friend’s mac already. no luck. Feels like the file itself is busted.
Sometimes moving it to another device works… like plug into a diff pc or try on mac? I know it sounds dumb but windows media player wouldn’t play mine while it worked on my friend’s macbook.
I tried that “convert/save” thing on vlc. it just spits out another file that also won’t play lol.
Ugh yeah I had this happen with a travel vlog once. if file size looks fine then it’s prob corruption. VLC “convert/repair” tool sometimes helps but don’t expect miracles.
I had this mp4 video i recorded last month from my cousin’s wedding. it played fine before but today when i tried opening it, it just says “can’t play this file” on both my laptop and phone. i even tried vlc, quicktime, nothing works. the file size looks normal so i don’t think it’s empty, but it just refuses to run. i honestly don’t care about anything else, i just really want this video back since it’s the only copy i have. has anyone here dealt with a broken or corrupted mp4 before? is there some way to fix this or am i screwed?
The wdfilter.sys BSOD is usually caused by faulty or outdated drivers or corrupted system files. To fix it safely, boot into Safe Mode if needed, update or roll back storage and system drivers, and run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth in an administrator Command Prompt. Install any pending Windows updates and scan for malware. If the issue started after installing new software, uninstall it. These steps usually fix the BSOD without affecting your files.
If you need to recover videos from your Mi Camera’s 32GB microSD card, don’t use the card anymore to avoid overwriting. Connect it to a computer using a card reader and try recovery software to scan for lost files.
Some good free options are Disk Drill, PhotoRec, Recuva, and EaseUS Data Recovery Wizard. They can help recover deleted videos and often let you preview files before restoring them.
If the files are important and the software doesn’t work, professional data recovery services in Singapore like Data Recovery Singapore, Ever Higher, Greenergy, or Accplus Technologies can recover the data safely. Always save recovered files to a different drive to avoid overwriting.
