WolfJT Posted July 15, 2015 Share Posted July 15, 2015 I am seeing the same thing with the SP3. I havea Sandisk 64 gig card. I did not see this issue with a 32 gig card. What is the size of your card? Link to comment Share on other sites More sharing options...

schoondoggy Posted July 15, 2015 Share Posted July 15, 2015 It is highly recommended to format them with this: https://www.sdcard.org/downloads/formatter_4/index.html Link to comment Share on other sites More sharing options...
DLCPhoto Posted July 15, 2015 Share Posted July 15, 2015 (edited) This is a known problem for various Surface devices, and I've seen reports involving a wide variety of brands and sizes. I've been unable to pinpoint what the specific problem is. In my case, I had a Lexar 633x 128gb card, UHS-I/U3, 95 MBps, which seemed to be the fast I could find, that kept unmounting under certain circumstances (connecting a USB hard drive, flash drive, etc.). I replaced it with a SanDisk Ultra 128gb (48 MBps), which has performed flawlessly. Edited July 15, 2015 by DLCPhoto 1 Link to comment Share on other sites More sharing options...
WolfJT Posted July 15, 2015 Share Posted July 15, 2015 I'll give this a try. Thanks Link to comment Share on other sites More sharing options...
