As many devices, like smartphone or camera, have limited built-in storage capacity, users tend to use a memory card for storing more data. But such card is vulnerable. So this article will expose its 8 most common problems and tell you how to fix them.
Like other kinds of data storage media, the memory card is susceptible to various problems. Once the card malfunctions, it’s very likely that its internal card will be in danger too. Therefore, it is suggested to back up your card data regularly. Data backups will make great effects in the event of card data corruption, just like PST recovery from PST backups on computer. However, if you do not have a current card data backup in hand when you suffer card issues, you’ll be required to make efforts to resolve them. Now, in the followings, we will unveil the 8 top memory card problems and their solutions.
1. Memory Card Is Write-Protected
Most memory cards come with a small switch. When the switch is turned on, you will be able to write data into the card. When you try, you will get related write failure error messages. In this case, actually, the memory card is write-protected.
Solution: This issue is very simple to be resolved. You can just turn off the switch. If it fails to unlock the card, you could proceed to toggle the switch back and forth several times and wait several minutes. After that, try to reuse it. If error persists, you have to format the card.
2. Card Cannot Be Used/Read
When you try to use the card, you may receive “this card cannot be used” or “this card cannot be read” error messages on the device screen. This issue is also very common.
Solution: In this case, you should restart the device, no matter camera or phone. And then retry. Most of time, the issue will be gone. If the error still exists, you have no choice but to back up the data and format the card.
3. Invalid File System in the Card
Sometimes, when you attempt to access the memory card on your PC, you may be prompted that the card has no valid file system. It either means that the card has no file system or its file system cannot be recognized by the PC.
Solution: In this scenario, you can firstly run CHKDSK to scan and repair the card. If it fails, you have no alternative to format this card. But notice that you’re better off backing up its data before format.
4. Memory Card Runs Slowly
Sometimes, you may feel that your memory card runs much more slowly when transferring data than before. Undoubtedly, it means that something wrong must occur to your card.
Solution: First, you can try to transfer a small amount of data to see if the speed is still very slow. If so, you can format the card, which may solve this issue.
5. Memory Card Cannot Be Read by Computer
If you want to access the memory card from your computer, you will usually use a card reader. At this point, it is also a frequent case where you find that the card cannot be read by your PC.

You may discover that some files on your memory card are missing, disappear or become unreadable for some reasons.
