SD card unmounting issue

[KotoriRose]

Since the last update, my L1 keeps saying SD card unexpectedly removed when the card is still in place and hasn't been removed. Is there anyway I can get it to work proper again?

Hi, you can fix the issue by unmounting and mounting SD Card, here are the steps:
Step1: Go to Settings and then to Storage.
Step2: Select the Unmount SD Card option from the Storage tab and then click OK to confirm.

Step3: After this, switch off your phone/device, remove the SD Card, wait for a while and then again put it back to the device.
Step4: Now, switch on your device and navigate to Settings and then Storage.
Step5: Select the Mount SD Card option, which will be displayed only when the card is unmounted.

Or you can format your card to have a try, but before doing so, you must make makeup in advance to avoid data loss, or you can just download the program Bitwar Data Recovery tool, I think it's a good one.

Hope it can help you anyway.
