Insufficient storage space & Insert SD card I'm using a Meizu M6, and a newly bought Sandisk Ultra micro SD XC 64gb.
Internal storage is about 1.67 gb free out of 16gb.

For the record, I have already checked the wiki tags and similar topics, as well as format, remount, cache clear, and/or reboot, but none of them worked.

So my phone and desktop can detect my SD, but:


everytime I tried to create an empty, new folder on my SD, it gave me the "insufficient storage space" message... despite being empty as a clean slate.
everytime I tried to use the camera, it gave me the "insert SD card" message... despite being able to detect it earlier.


Yet I can create new folders and move items to my SD if I connect it to my PC with some card reader.

What might caused this? Any pointers?
you could try using the Windows partition manager to format the micro sd card and create a brand new partition. You could try using the tool h2testw to check if the card is damaged or authentic.
