What Causes the Error SD Card Is Blank Or Has Unsupported File System

How to Fix SD Card Is Blank or Has Unsupported File System

Since the error message doesn’t elaborate on the details about the problem, it’s almost impossible to know the reason behind it in the first place. But based on cases reported by users around the world, we have managed to glean several common causes:

  • Unsafe removal of the SD card
  • Removing the SD card without turning off the device to which it’s connected
  • Connecting the SD card to a computer afflicted with viruses
  • Frequent connection to devices of different operating systems
  • Corrupted system files

Basic Methods for Solving the Error SD Card Is Blank or Has Unsupported File System

Method 1: Reboot

Sometimes the error occurs owing to a random configuration failure, which can be fixed simply by rebooting the device.

Method 2: Reinsert the SD Card

Users have reported that slots reserved for holding SD cards might malfunction occasionally. If that’s the problem facing you, try taking out the faulty SD card, inserting a working one, and then reinserting the faulty one several times to make sure that the problem doesn’t result from slot failure.

Method 3: Show Hidden Files

The reason for this kind of problem is that some hidden file left by previous operating systems remains on the SD card, deluding the current operating system into believing that the SD card is formatted with an unsupported file system. To fix it, you can delete those hidden files by using these steps:
