Windows 10: SSD with USB interface for Storage Spaces

According to https://support.microsoft.com/en-us/help/12438/windows-10-storage-spaces (pull down the top item):


"You can use a variety of types of drives with Storage Spaces, including USB, SATA, and SAS drives."


However, when I wanted to use a USB flash drive to create a storage pool, the Storage Spaces Control Panel said: "No drives that work with Storage Spaces are available."


Will a SSD with a USB interface work for Storage Spaces?

:)

 

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.

 

SSD storage keeps filling up on its own

Hi Ash,

There's a possibility that the files are just hidden. As an initial troubleshooting, we suggest following the steps below on how to display hidden files that's eating space of your SSD:

• On the Search bar, type folder, and then select
  Show hidden files and folders from the search results.
• Under Advanced settings, select Show hidden files, folders, and drives,
  and then select OK.

Keep us in the loop with the result.
