Best Practice for Ejecting / Dismounting Storage Space

Storage Spaces - anyone know how to "safely remove" one?

  I have three USB external drives pooled together in a single Storage Space, love it.  But I can't find out how to unplug the USB plug (or undock my Surface) safely.

  If I just remove the USB/undock (as I've been doing so far), it hasn't really failed catastrophically, but it has to do repair quite often - causing terrible performance on the pool but also definitely not good for me to be causing problems.  I don't want to destroy my data.

And one other Storage Pool question: my Surface Pro 3 reads my Storage Pool file in Windows 8.1 (where I created it) and in Windows 10 (dual boot). But I see threads mentioning not being able to access the pool after a clean install. I thought I could plug those 3 drives into any Windows 8.1 PC and access the

Hi,

When you unplug hard disk from storage pool, it is actually the process of hard disk replacing. Refer to Storage Spaces Frequently Asked Questions (FAQ) How do I replace a physical disk? section, there are instruction about how to remove a hard disk from storage pool (command, PowerShell)

http://social.technet.microsoft.com/wiki/contents/articles/11382.storage-spaces-frequently-asked-questions-faq.aspx#How_do_I_replace_a_physical_disk

Storage Spaces records information about pools and storage spaces on the physical disks that compose the storage pool. Therefore, your pool and storage spaces are preserved when you move an entire storage pool and its physical disks from one computer to another. But it is good for Windows server 2012 and I am not sure that it also applies to Windows 8.1. Since we do have limitation on this kind of test, I hope someone could do the test or search some information online for us: )

That works to remove a drive from the pool, but it also erases all the data from the disk and requires that the remaining disks have enough space to take on that load.  This is not my goal, and I don't want to move or erase data.

I have 3 drives plugged in (one single Storage Space).  All drives connect to a hub, and then to my Surface.  I want to take my Surface with me, but I can't figure out how to warn Windows that I am about to unplug all the drives.  The "safely remove hardware" doesn't work.

Are you still having the problem?

Have you tried to power off your Surface Pro 3 first then unplug the external drives?

You know I think I'm willing to just go with that.  It seems like Storage Space is probably really best designed for servers, or at the very least a steady state machine that isn't subject to hot-swaps all the time.
