Category of errors in SD card

First of all, you need to know that your sd card belongs to which category of errors does. The SD card errors can be prompted by:

Primary Category

  • Bad sectors
  • Corrupted file system

Secondary Category

  • Adware/malware/virus attack
  • Inappropriately inserting or ejecting SD Card

There are many problems that allow you to say that your SD card is corrupted. Both Hardware and Software level issues can be responsible for corrupting your SD card. For instance a corrupted file system or virus could possibly be responsible for errors. Also inserting and ejecting the SD card improperly and bad sectors can lead to SD card corruption. Let’s discuss in brief a few of the most common errors.

The pseudo corruption

It is possible that you might be trying to store a file that is more than 4GBs in size. SD cards are FAT32 formatted out of the box. And the FAT32 format has a maximum size boundation of 4GB. So it could possibly make you think that the SD card is corrupted. But in reality it is the file size that is the cause of the error. Thus this issue requires no further clarification. You just need to reduce the file size, if possible. And if not try formatting the SD card in exFAT. But keep in mind two factors. First one is that, not all smartphones support the exFAT format and the secondly you are going to end up losing all your data.

At least I am not, so if we are on the same sides then the next half of the article is important and quite informative.

Though it will show all the files during the recovery process but will not be able to recover all of them. There is also an unofficial android app for video and image recovery.

In other words, fixing up a corrupted SD card has just one solution on Android i.e formatting. Though there are many data recovery apps for Android like EaseUS data saver, Disk Digger, etc.
