Random Local Disk (D:) Appearing in PC management

[GilaStomper]

I have recently had a 500mb D: Drive appear out of nowhere and I can't seem to remove it or even see the files that are present on it. How do I remove it, as my Disk management is only letting me select "Help" as an option.

I had the same thing happen. Maybe it's the newest Windows 10 update?

Maybe, I've been getting endless your running out of Disk Space Messages!

I'm guessing Windows 10 was not initially installed to a drive devoid of partitions so that it could make partitions of the correct size?

Normally, Windows has a small, hidden partition for it's own purposes, but the size of this partition has grown over time. If your small partition is too small, Windows makes another one that has enough space.

The simple solution, being Windows 10, is to remove the drive letter and ignore it, or reinstall Windows, cleaning off any existing partitions during the process and having only the one boot drive physically plugged in.

I just notice that today too! I thought it was something that would affect my laptop's performance. I just bought my laptop a few days ago. It's an XPS 13 9370 with 512GB SSD. Is it due to the Feature update to Windows 10, version 1803? My other laptops had trouble updating this new update for a while, tried 4 times and failed. But this new laptop seems to update just fine on 5.29.18. I haven't retried updating the other laptops with this new update yet so I can't tell.
There isn't any file I can't see in the Local Disk D: but it's almost full. When I restarted my laptop, it showed less full. Not sure why.

'D' on Disk 1 is labelled "OEM Partition" - - that's the laptop manufacturer's Recovery partition. You are not supposed to be able to see it's data.

Normally it shouldn't have a drive letter assigned to it in order that it's only visible in Disk Management and nowhere else.

Somehow yours has been assigned a drive letter - - this drive letter should be removed to rectify that situation, or just leave it as is and don't mess with it wherever you see it in Windows.

Whether the original recovery partition was too small, causing the Windows installer to create a newer, larger one, or the original partition was missing it's NO_DRIVE_LETTER attribute, don't delete the partition, just remove the drive letter.

If Disk Management doesn't allow you to remove the drive letter, you can remove the drive letter by opening an Administrative Command Prompt and issuing the following instruction:

mountvol d: /d

This will remove the mount point for drive letter d: and your extra partition will no longer pester you through Windows Explorer. Of course, if your extra partition is not drive letter d:, use the correct letter for it.

And of course, don't remove drive letters for partitions you want to access unless you know how to put them back.

That is an after effect of the 1803 update for Win 10.

Easy removal of that drive letter, here:
