STEP 1. Re-install disk drivers to fix blank and unsupported SD card 

One of the most frequently used troubleshooting methods for a removable drive is to update disk drivers. If your SD card cannot be detected or recognized by the computer or device, here we have two methods for you to fix it:

1. Unplug your SD card and connect it to the other device, or PC, to see whether it can be read or not.

2. If the other phone or PC cannot read the blank SD card, connect it to a computer, and try to show hidden device driver and reinstall disk drivers as instructed.

• In Windows 10, for example, type cmd in the search box and right-click "Command Prompt", then choose "Open as administrator".

• Type set devmgr_show_nonpresent_devices=1 at the command prompt interface. Then input "start devmgmt.msc" and hit Enter.
• Next, "Device Manager" will open. Click the "View" tab and select "Show hidden devices".
• Now expand the "Universal serial bus controller" section.
• If you find any grayed entries > Right-click on it > Select "Uninstall".

Reboot the computer and the drivers will be automatically re-installed. Connect the SD card to your mobile phone, and it should be fine now.

STEP 2. Run chkdsk to fix blank and unsupported SD card 

If it still cannot be detected by the computer, there might exist some internal errors, like file system corruptions, that results in a blank SD card. Then, you can run chkdsk command to get the unsupported SD card fixed.
