Windows 10 Anniversary Update Might Hide Partitions After Install

One of the issues experienced by users after installing the Windows 10 Anniversary Update concerns partitions, as many of those who upgraded their computers reported that a number of partitions disappeared from File Explorer.

Furthermore, all partitions show up as RAW in Disk Management, which makes most people believe that all their data has been removed and nothing can be recovered.

Microsoft, however, claims that this is just a bug discovered in the Windows 10 Anniversary Update install system, and while no files are lost, it’s critical for users not to try to recover anything with third-party apps because this could lead to completely breaking down the partitions and removal of data.

“Microsoft is aware of this issue and is working on a solution to be released through Windows Update. Any data you have stored on the affected partition is still there. We recommend that you not try to recover or otherwise write data to the affected partition, nor should you format the partition,” the company says.

You can also downgrade in the meantime
Microsoft’s Sharath Srinivasa goes on to explain that a patch will be released to users when it’s available and states that users who do not want to wait for it can always downgrade to their previous Windows version. Partitions should be then just as you created them, with all files once again accessible.

For the moments, there’s still no timing on when exactly the new patch could land, but since the company is already aware of the bug and working on a fix, it should take too long before it gets the green light.

The Anniversary Update is currently available to Windows 10 users free via Windows Update, and the release takes places in stages, so more people could experience the bug as they complete the upgrade. For the moment, Microsoft says that it has received only “a small number of reports” pointing to this bug, so not too many people might be losing their partitions after installing the Anniversary Update

This sort of thing will continue on with W10 Home and Pro unless users intensively complain and campaign to have M$ stop it.

Satya does not have users' best interests with forced updates; a broken user system via a forced Windows Update is worthless...

If breakages due to Windows Updates were not such a huge issue, then M$ would not publish Enterprise and Enterprise LTSB.

5 to 10 % of all Home\Pro users experience some form of serious problem with Windows Updates - and that is a HUGE number.

It's an egg in every Home and Pro user's face...

the problem that i have (i have investigated in spanish forums) is that my usb HDD would not be recognized by windows 10, despite the fact that in others pc works without any problem, in some cases the HHD would appear as RAW disk in disk and microsoft havent give any answer to us about the issue

I guess I have been lucky, mine show fine, I can access them.
goes to show the randomness of this bug I guess.
I'm running WIn10 Pro x64.

To be honest with you, I did not experienced any problems with the new update. Maybe because I have waited until the 10th of August to do it. But so far, no problems of any kind.

it is not a new partition it is only the system unit that is now visible to your eyes, just that, nothing to worry about

When did your data partition disappear?

When did your data partition disappear?

Since I created it after windows installation from diskmanager, but it wasn't showing up even after assigning drive letter manually, but after anniversary updates I just reassigned the drive letter & it's working now.

There were no other partitions until i did the update!

basically when you install windows, it creates two partitions (or more based on your preferences) however one partition is hidden and contains info about your OS (recovery parameters etc) and the other one is where windows will install its files.


normally it will look like this, please note that i´ve unhidden the partition i mentioned above

Very bad issue.

It seems the cycle of issue goes like this.

Some recent laptops/desktops will not suffer in any of this issue because the hardware/software are already up to date.

Meanwhile majority which are purely old and attempt to upgrade may suffer some minor to major issues.

is not a driver nor hardware issue, since some problems may appear even if you do a clean install (in my case it was like that) that being said it is a OS bug!! and considering that there are a lot of people with the same problem as mine with different config and settings
