Windows 10 Mobile not only allows to store all that you want on expandable storage using a SD Card but you can also install apps on MicroSD Card (Read our tutorial). This makes Windows 10 Mobile one of the most flexible OSes around. Now in case you are not using a fast enough (less than Class 10) MicroSD card you may have encountered “Scan SD Card & Fix Errors” message time and again and at the same time it can lead to some issues like random “resuming / loading” screens. This happens because of poor compatibility of the default SD Card File System FAT32. While we can’t fix the slow response of Class 2 and Class 4 MicroSD cards we can help you in getting rid of this annoying error messages and stability issues. Keep in mind that you can use this tutorial for Class 6, Class 10 and UHS U1 / U3 cards too if you are facing random performance issues.

Steps:

This will make your data on SD Card deleted completely so take a backup somewhere.

  1. Remove the MicroSD card from your phone by simply powering it off and removing; or by going to Settings–Storage–>SD Card–>Remove. If you just power-off and pull SD Card all your Apps / Games on SD Card will still be listed in App List and that may help in reinstalling them later.
  2. Now use the PC adapter with SD Card and insert into a PC you have. You can use Adapter and PC of your friends if you don’t have either.
  3. Go to My Computer / This PC, Right click on the SD Card and choose Format.
  4. Now you can choose “ex-FAT” as the File System. By default it will be FAT32, which is the oldest known file system. ex-FAT, being the latest is much more compatible than FAT32. You can also choose NTFS as File system, as Windows uses NTFS File system by default. We however recommend ex-FAT.
  5. Allocation unit size can be set to “Default Size”.Ex-Fat format
  6. Format the SD Card. Right click and choose to eject.
  7. Once done you won’t face this annoying message anymore while using this formatted SD card in your windows 10 Mobile phone. This also helps in fixing random performance issues on you device happening due to SD Card.

This tutorial works very well for even Class 2 / Class 4 SD Cards, but while you can use a Class 4 MicroSD card for apps / games installation, the experience may be sub-par. That’s why we always recommend minimum Class 6 MicroSD card for better performance (Read our tips on improving Windows 10 Mobile performance).
