Also, I downloaded some songs from a known website the last evening, and virus could have infected my phone then, although I have previously used the website with no problem. The card could not have been damaged because it was securely installed in my phone when this happened. I would like to know the cause of this random error. I also tried formatting via Disk management on PC. I also tried easeUS Partition Master to format the SD Card on PC, with no result.

I scanned my SD card with two antiviruses with no result. Though the backup version of the data that I have saved in my PC behaves normally and gets permanently deleted if I delete it.

Also, if I manually delete the files from my SD card, they come back after a while. I tried formatting with quick format on and off. It would not get formatted, and show the message- 'Windows was unable to complete the format'. I then tried backing up the data and formatting the SD card on PC. Without the SD card, the phone runs fine. Now, whenever I shutdown the phone with the SD card on, it hangs in the middle of the process, and I have to remove the battery. I waited and after some minutes removed the battery and restarted. I tried to shutdown my phone, but in the middle of the shutdown process, the phone hanged. All my apps and data installed on the SD card were missing.Īfter some time, the notification vanished, with the problem persisting. Then it started suddenly, and I noticed that there was a notification- 'Preparing SD Card, Checking For error'. There was no response from the phone for some time, which was unusual. In the morning, I tried to start my Android 4.4.2 phone.
