Allow sync to external devices
Currently, syncing OneDrive to an external device (Such as an external HDD) is unusable. It is impossible to keep synced up, and will constantly prompt for the user to to re-sync their OneDrive, defaulting to C:\Users[User]\OneDrive. After attempting this for a few months, I finally bit the bullet and accepted that syncing OneDrive to an external device is unusable in its current implementation.
To resolve this, I would suggest the following:
OneDrive remembers where it was synced - even if the drive is no longer present. So rather than starting the initial setup, the user would receive an error along the lines of "OneDrive not connected. Do you wish to reconfigure?" with the option to say no, and stay unconnected to OneDrive on this machine. Currently, no matter what is pressed when the drive is disconnected, OneDrive will start the initial configuration.

Honestly this shouldn't be on uservoice, but rather in their issue backlog filed as a bug.
They obviously wanted to implement the feature which was supposed to work. This isn't working, should be fixed without having to rely on the vote count.
Yes, this. I use a Drobo at my business workstation. When I'm on the go, I always have to remember to exit OneDrive, otherwise I have to go through a long process of reconfiguring OneDrive to sync to my external location, agree that a OneDrive folder already exists, it will take hours to rescan every subfolder, and then find the small amount of things that have actually changed.
At a minimum some kind of check to determine if the Volume (HDD) is available.
The side effect if you have an external that goes into power save and OneDrive cannot ping it is rather than "failing safe" it will think you've deleted everything and proceed to remove it from your other devices!
If you want more people to move to cloud you cannot have a situation where a powered down or disconnected HDD can splash all your digital assets stored on OD.
I had this happen to me today. Did not occur with my Google Drive files. Only OneDrive.
