I just installed the last Windows 10 Features Update, version 1803 (the one with Task View) and suddenly a Local Disk (E:) that was not there before has appeared in my computer.
Normally there would only be two drives listed in This PC: Windows (C:), which is a Samsung SSD 850 EVO 1TB, and a DVD/CD drive. That's all. But now after this update there is this E drive which is listed as nearly full: "39.9MB free of 508MB". In Disk Management it appears listed as a OEM Partition (in addition to another OEM Partition, a 500MB "Recovery Disk")
If I run the Samsung Magician app, which I use to mantain my drive, this E drive is also listed there as a separate drive (whereas the other OEM partition, "Recovery", has never been listed there or in This PC)
Annoyingly, now a notification keeps popping up warning: "Low Disk Space. You are running out of disk space on Local Disk (E:). Click here to see if you can free space on this drive" But clicking there doesn't free anything.
I have tried running the Hardware and Devices Troubleshooter, which innitially found a Restart pending. I restarted but drive E is still there. Running the Hardware or Updates troubleshooter again finds no issues.
How can I get rid of this drive E so that things are back to normal and I don't keep getting that notification?
