Causes of SD Card Getting Corrupted

A corruption error message may appear when SD and MicroSD cards have been used on many devices or have been forcefully removed from a computer while a file is being viewed or transmitted.

Other Methods

Here are some strategies you can try if you suspect your Android smartphone’s SD card is corrupted:

1) Update your Android with New Version

A system update can fix several problems associated with accessing files stored locally and on SD cards. So, keep your system up to date. This way you can also avoid any operating system related bug that may be incompatible with the card you are using.

2) Check if you have mistakenly placed a SIM card instead of an SD card

Are you using a SIM card? It can be easy to confuse SD cards with SIM cards if you’re new to Android smartphones and tablets. The SIM card enables cellular network functionality and can’t be used to store apps, media, and other data.

3) Use Cloud Storage instead of an SD card

If you’ve used an SD card to make space on your Android phone, you might think about switching to a cloud storage service. Cloud storage services like Google Drive, Dropbox, and OneDrive can back up photographs and videos to an internet server as soon as they’re made, so you don’t have to worry about them filling up your phone’s storage space.

You may also use other devices to access all of the content posted to your cloud account without physically moving an SD card or USB drive back and forth. There’s also a low chance that these files will be lost due to corruption or card failure.

How do we protect SD cards from being corrupted?

At any time, your SD card may get corrupted. As a result, you should preserve your data by taking care of it and protecting it from any data loss circumstances that may emerge. The best advice is to always buy and use branded SD cards, cheap ones have more chances of getting corrupted.

Make backups– The most effective technique to secure your data is to make backups. You may quickly restore a duplicate of the working file and continue as usual if data is lost.
