Surface Pro 3 Woes – Expanded Memory

I just recently got a Surface Pro 3 for work and I absolutely love it. It truly is a replacement for a laptop… and when you consider that the new SP3 weighed almost as much as my previous laptop’s power brick, it’s a welcome change. There have been a few things that have been bugging me, but most of them I have overcome – the latest one was an unusual problem and seeing as there’s very little info out there about it, I thought it might be worth sharing.

It was always my plan to use an SDXC card to store Videos, Music and my OneDrive files. These are all things where the I/O speed is not particularly important, and portability (being able to transfer from my workstation at home to my Surface for work) is… so when the SDXC card stopped working after about 30 minutes I couldn’t believe it! I Googled around for people in similar situations and it appears as though it used to be a common problem… but most of the current issues seemed to be hardware-related – all of the power-management issues have been resolved with firmware / software updates from Microsoft themselves since the start of the year (, The temporary fix (for me) was to take it out and put it back in again, but that only worked for 1/2 an hour at a time… and in the meantime the OneDrive App switches off because the drive it’s supposed to be writing to no longer exists.

What’s a guy to do? Initially I thought there might be some power management feature setting somewhere that is causing it to shut down after a bit of inactivity, but there were no drive power settings in my Power management control panel applet – maybe they’re hidden on the SP3?

Well… the easiest way I found to have it stay connected and dodge the power management shenanigans is to go to Device Manager and under the Properties for the SDXC drive, change the Removal policy from “Quick Removal” to “Better Performance” – This prevents the Power saving settings from switching it off. Anyway, problem solved!

Now I just need to find a way to remap some of the keyboard settings and I’m a happy camper! I’ve done it before, just need to remember where the registry keys are…
