Local Disk (E:) randomly appeared and is full?

Recently, I've been getting notifications saying that Local Disk (E:), which hasn't been available prior, is full (42.0 MB out of 449 MB) and prompts me to clean it, but nothing is inside it?

What I'm wondering is what exactly is Local Disk (E:), is it affecting anyone on my computer, how do I clean it, and should I (somehow) get rid of it?
This is a known issue with 1803. It has been happening with new update that new drive is getting uncovered and you start getting low space notifications. You can do following to hide it and there will be no harm anywhere.

Type diskpart in Windows Start Search box (Cortana) > Right click on Diskpart and Run as Administrator
Give following command and Enter:
select volume e
Give following command and Enter:
remove letter=e

Hi , this is a known issue in the 1803 Update,

It is the recovery drive, you are not meant to see it, it is not meant to have a drive letter, remove the drive letter and everything will return to normal:

Click your Start Button, type cmd, then right click Command Prompt and choose 'Run as Administrator'

Run this command and hit Enter

diskpart

Run this command and hit Enter

select volume E

Run this command and hit Enter

remove letter=E

Close Command Prompt

That's It!

Microsoft is aware that previously-hidden partitions are improperly being assigned drive letters after installing the April 2018 Update.  As a result, they now appear in Disk Management and File Explorer.  These partitions are typically recovery partitions used by the Windows Recovery Environment or by the Original Equipment Manufacturer.  It is not recommended that you attempt to delete or reformat these partitions as this may have adverse effects on your ability to recover Windows.  Microsoft is currently working to address the issue in a future Windows Update, and we’ll update this thread when a solution becomes available. 

(Update 5/14/18:  The solution that will soon be released via Windows Update will only prevent this issue from occurring for devices that install the April 2018 Update after the solution is released.  If you've already installed the April 2018 Update and are experiencing this issue, you'll need to follow the steps below if you want to hide these partitions.)

Although you can safely ignore these partitions, if you prefer do away with the low disk space warnings and hide the partitions so they no longer appear in File Explorer, you can do so by manually removing the partition’s assigned drive letter.  To do this:

1. Select the Start button, type cmd and then right-click Command Prompt in the search results and select Run as administrator.

2. In the Administrator:  Command Prompt window, type diskpart and press Enter.

3. Type list volume and press Enter.

4. Make note of the volume number for the drive letter you want to remove.  For example, if the drive letter you want to remove is Drive “E ”, note the volume number for Drive E.

5. Type the following command, and press Enter. 

 select volume 

When typing this command, in place of substitute the volume number you made note of in Step 4.   In the example above, if the volume number for drive E is 5, you would type: select volume 5

6. Type the following command and press Enter.

remove letter=

When typing this command, in place of substitute the drive letter you want to remove.  In this example, you would type: remove letter=E

7. Close the Command Prompt window.

Best,
Andre
