How to Sync OneDrive to a Removable Micro SD Card in Windows 10

SkyDrive Sync to Micro SD

There has been many changes to OneDrive over the years and across the different Microsoft Windows versions; from Windows 7, to Windows 8 and 8.1, and now Windows 10. However, one thing has remained the same, OneDrive’s inability to work on removable drives right out-of-the-box. We were able to overcome this in Windows 8 with this earlier tip.

Why would you want to do this?

The main reason is because your computer or tablet has limited space, generally between 64GB and 512GB. This system drive is typically a lot faster than removable drives, so it is better used for applications. However, once you install your necessary (and unnecessary) applications, like Microsoft Office, Adobe Photoshop, Minecraft and a myriad of other programs; your available free space gets fairly small for your own personal data, like documents, pictures, music, videos, and other files. This is where OneDrive’s cloud storage and a large removable drive can work together very well. For example, I practically doubled the storage on my 128GB Microsoft Surface Pro 3 with a new 128GB micro SD card inserted behind the kickstand. Here’s the one I’m using from Amazon.

How To

So here’s how to get around it in Windows 10 (thanks for the tip Brian!). If you’re a tech geek, format your removable media as NTFS, create a dynamic virtual hard drive on it, and point OneDrive to the virtual hard drive.

If you’re not (yet) among us tech geeks, below is a step by step guide on how to get OneDrive to sync data to the removable drive. I have broken the major steps into multiple pages to make it easier to follow (unlike my earlier super-lengthy article on How to Sync SkyDrive to a Removable SD Card in Windows 8).

Once done, OneDrive works as it would with a regular drive. You can directly work on the files and move them to and from the OneDrive folder fine. OneDrive synchronizes the files to and from the cloud fine as well.

Removable OneDrive Quirks

One major concern is, “What if I remove the micro SD card?” Well, if you remove it while it is actively reading/writing, then you may corrupt your data. This would happen to any removable drive whether it is connected to OneDrive or not. Because OneDrive does a lot of file syncing in the background, it is hard to know whether it is active or not. Therefore, do not remove the micro SD card or USB drive without right-clicking the drive and ejecting it first.

If you remove it after properly ejecting the drive, it should be fine. I have had to remove my micro SD card a few times to access other micro SD cards from my Windows Phone and cameras. Here’s what happens when you do. Below is a screenshot of the micro SD card removed on my Surface Pro 3.

File Explorer; No MicroSD or OneDrive VHD

Now, if you try to access your OneDrive, you would get a “Location not available” and/or an unable to find OneDrive dialog box(es).

Location is not available; Click okay

04 Unable to find OneDrive; Click close

Once I inserted the micro SD card, the drive appears in File Explorer.

File Explorer; Inserted MicroSD

Trying to access OneDrive now would yield the same one or two “Location not available” and/or an unable to find OneDrive dialog box(es).

Once you remove your removable micro SD card or USB flash drive, the virtual hard drive file with the OneDrive folder on it gets disconnected from the OneDrive service. When you re-insert the removable drive, the virtual hard drive does not mount automatically, so OneDrive cannot find the virtual hard drive and OneDrive folder. So to solve the problem, you just have to remount the drive and reconnect OneDrive. Here’s how to do it:

Step 4a: Re-Setting Up One Drive

Unfortunately, this does not only happen when you remove the drive, it also gets disconnected after a system restart. Luckily, OneDrive works fine after putting the computer to sleep or shutting it down. So to get OneDrive to work again after a restart, you would have to remount and reconnect as shown in Step 4a: Re-Setting Up One Drive.

Hope this works for you. Let me and others know in the comments if you guys find a better way. Thanks!

    There is a way to prevent the unlink in every restart. It is a bit tedious, but one can set up a task to mount the virtual disk via Diskpart, then a delayed start up for onedrive (disable onedrive on startup first). It works. I can post the script if interested. I Bing’d it and there lots of examples, but I could only get the Diskpart one to work.

      Very interested to try this method. Some reason when doing Windows Updates in Windows 10 it is not allowing this install after shutdown/power on. It still tells me to restart PC, which removes the mounted drive of course and the whole sync process again.
      If you could please let me know how to do this I would like to try it out and see if it works for me. Thank you!

    Brian, These are well done instructions. In the IT biz, I know great user guides when I see them! Nice job.
    Yes, I would like the script when you get a chance. I did the set up just before the full Windows 10 update, which disappeared the connection. Will take your advice to reduce the occurrence,
    Thanks again for your input!

    Thank-you sooo much for this! Excellent instructions!
    I have the same question as someone else in here. I’m a bit confused. Since my files are now set to go to the Virtual Drive; and uploaded to One Drive; does this mean that the files are not stored locally on the sd card or does it go to both?

    From today:

    Allow OneDrive to sync to removable media on Windows
    Working On It → Boom! It’s Done

    With today’s release, OneDrive now supports syncing to removable media on Windows 10, 8 & 7. When setting up your OneDrive, you can choose a removable media target for your files.

    Been talking with OneDrive… At today’s date they say OneDrive has to work in the primary storage…. Well….. So my question is, for you…
    Wht’s the difference in creating a VHD or just create a folder in the micro SD?…
    Also You apply the same about the VHD if you use a USB?.

    Thank you for this post is very useful.

    My plan changed and now I have less storage capacity and I would like to reduce the size of my * .vhdx file. Do you know a tool that works on windows 10 home edition? (from a tablet)

    Very well done instructions, thank you. However, it seems that the auto-mount problem is still real in September, 2017. Or at least I have not found something in Windows 10 to auto-mount the VHD and sync OneDrive.

    Anyone have an update on this? Or do I still need to use scripts to auto-mount the VHD and delay the One Drive at startup? Thanks!

    Thank you SO much for such wonderfully straightforward and well explained step-by-step instructions. It is working and is exactly what I wanted to do when I purchased a new SD card.
