Surface Pro3 - MicroSD is not working

I nad exactly same problems with my new / fully patched Surface Pro 3: miniSD Card not working / not recognized. Solution mentioned ealier worked.

So, the exact steps below:

1. Open "Device Manager" and find non recognized device in "Other devices"
2. Righht-Click and use option "Update Driver Software..."
3. "Browse my computer...."
4. "Let me pick from a list ...."
5. from the list fine and click on "SD host adapters"

6) Choose the last one: "USB Mass Storage Device" - do not choose any "Related USB Card Reader devices"

... and SD Card should work from now.

Why Microsoft didn't publish such list for the last several months I could not imagine. Surface 3 is wonderful device with only minor problems, that could be easily addressed.

Dear Zack,

I am also having this issue with my i5, 128GB Surface Pro 3.

My microSD is 64GB Sandisk Ultra.

Formatted to exFAT.

There were no issues when I use a USB reader.

Please help. Thank you

Hi, I was having the same issue on my SP3 i5 256GB tring to install a Sandisk 64GB micro SD. I kept seeing it pop up as USB 3.0 with the question mark and figured it was a driver issue. I downloaded the latest surface drivers from Microsoft and it came with the Realtek drivers. I tried again and again to no avail so then I tried the option in device manager to 'let me choose which driver to install'. There was a long list of the Realtek drivers from all my attempts but at the bottom there was a generic USB 3.0 SD driver. I installed that and WALLA! no more issues it mounted right away. I hope this helps everyone else having problems, for me the Realtek driver was the issue.

Reformatting card to NTFS fix it

By chance, do you have a desktop or laptop that has a SD card reader?  If you do, put the micro-SD card in its adapter, put it in the SD card reader and reformat it "exFAT" and try that.  Or put the card in a digital camera and try reformatting it, with it.

Then try the micro-SD card in the tablet.  Some people who managed to get a 128GB card had some luck with "exFAT" for the format.

If it still does not work but works fine with a camera or another computer, it will just plain not be compatible with the tablet.  Also, double check to make sure the card is a Class 10 card as well.  I do believe that all 128GB micro-SD cards are now, just to make sure.

Picked up a Surface 3 w/ 4mb RAM 128gb Memory. Bought a San Disk Ultra 64gb micro sdxc plugged it in nothing. Slapped into an adapter and tried with my laptop and it worked no problem. Tried reformatting to NTFS still did not work.  Reformatted to "exFAT" after to reading this thread. Worked after I popped it in! On reboot it still worked! Thanks!

Hello Surface Pro3 - MicroSD is n...,

Thank you for reaching out to us with this issue. I understand that your MicroSD is not being detected as expected on your Surface Pro 3. I'll do what I can to help you with this issue.

Your issue is similar to but not quite the same as this thread.  For now, your device manager method may be the best solution to this issue. However, we do have a couple questions for you regarding this. First, if possible, try using a USB reader instead of the Surface device. Do you still have the same issues with a USB reader? Also, what file system was the card formatted with?

Please let us know, and we'll continue looking into your issue.

Best Wishes,

Zack_T

Thank you everyone for your suggestions.  This morning I shutdown my Surface, restarted at work and behold, the SD card is now recognized.  Thank you very much for the quick responses.  Fingers crossed it continues to work just fine.

Also, FYI, once it mounted I did format at NTFS so I can move over any size file I wish.
