Windows 10: Reserved Storage Information

I'm looking for information about the New feature of reserve storage and how can I disable it.

:)

 

Why some unaccesible space is reserved in a storage?

Much like qubit said, for powers of 2, yes. But lately you are seeing SSD's with 120GB or 240 GB capacity, etc. They are automatically reserving the extra space, so a 240GB SSD now has the same storage space as one listed as 256. They've just set aside 16GB for wear levelling, etc.

 

Conflicting information on my Storage Space...


From disk management, it does report the same storage and used space as from explorer.
May I ask did you try to create a storage pool or something ? if so, you should not mess with this.

Is this disk an external disk connected via USB ? WD or Seagate branch ?

I have the feeling that this disk is formatted with GPT type using 512K emulation so Windows get confused. To verify:

1. Right click on Disk 6 ->Properties->Volumes. What does it show on partition styles ? GPT ?
2. Download Best Free Partition Manager for Windows | MiniTool Partition Free, install then run. What does it show on disk 7 ? MBR ?

If step 1 shows GPT and step 2 shows MBR then definitely the disk was formatted using 512K emulation. The reason they did this so that it would be recognized by WinXP or if you connect it to a TV.

Windows Updates failed is another problem you have. First, it tried to updates from 1703 -> 1709 and failed so any subsequent updates to 1803 also failed.

 

System & Reserved almost full?

Thank you for the information and posting back.

High System & Reserved memory usage could be due to the following:

• High Windows.old file(s) size
• Large cache of trace files size
• Windows 10 system file issues

We would like to know some information to better isolate the issue:

• Do you have a C:\windows.old folder on your C: drive?
• Which Windows version and build are you using? Type winver on search box and press
  Enter.
• What troubleshooting steps have you done so far?
• Can you post a screenshot of what is inside the System & reserved storage? Double-click System & reserved. See picture below for reference.

We will wait for your response.
