Windows 10: Storage Spaces with Boot Disk

I have a new laptop with a single SSD on a PCIe controller, Win 10 Pro. That SSD is my boot drive. Can I add a second SSD of exactly the same model and size and create a mirror without data loss?It seems that a long time ago it was not possible but now might be different. I can't get solid answers. What is the latest?

last free disk space after defrag in windows 10had

HI Joshua,

Thank you for posting in Microsoft Community and being a part of Windows 10.

I understand your concern about free storage space after performing disk defragmentation and disk clean. Do not worry, we will help you with this issue.

I would like to inform that the disk defragmentation might have taken up hard drive space if there are errors on the drive.

Try the below troubleshooting steps and check if it helps.

Step 1: I suggest you to scan for the shadow storage created on your device as this might be consuming the free storage space.

Follow:

• Log-in as an administrator.
• Press Windows + X keys from the keyboard, click on
  Command Prompt (Admin).
• 
  Accept the UAC (User Account Control) prompt.
  
• 
  Type vssadmin list shadowstorage into the command prompt
  
• 
  The results should tell you the amount of storage used and the maximum amount allotted.
  
• 
  Type vssadmin Resize ShadowStorage /For=[your hard disk]: /On=[your hard disk]: /MaxSize=[how much space you want to allocate]
  
• 
  You should get a message saying successfully resized the shadow copy storage association, and you should have more free space on your hard drive.
  

You may run a scan disk command to remove the bad sectors from the hard drive and then run disk cleanup and check if it works.

Step 2: I suggest you to
Run check disk (chkdsk) and check if it helps.

Chkdsk: The
Chkdsk (Check Disc) scan will try to identify and repair bad sectors found on the hard drive. Any data present on these sectors might be lost in the process. The computer can also go into a no boot state. Proceed at your own risk.

Follow the below steps:

• Press Windows + X keys on the keyboard, click Command Prompt (Admin).
• In the Command Prompt, type the following command, and then press ENTER:
  
  chkdsk /f
• You may be asked whether to schedule this volume to be checked next time when you restarts (Y/N).
  
• Press Y key on the keyboard and press
  Enter key.
• Restart the computer and check.

Hope it helps. Get back to us for further assistance on this issue. We will be happy to help you.
