What Causes This Memory Card Cannot Be Used?

How to Fix This Memory Card Cannot Be Used

In most cases, except for prominent physical damage, the error this memory card cannot be used seems to pop up for no reason. But when we looked into several scenarios posted by users, there were some shared causes among those faulty memory cards. Below are some of the most common:

  • Incompatibility between the memory card and the device
  • wrong ways of inserting the memory card
  • unsafe disconnection of the memory card from the device
  • Memory card corruption owing virus or other common errors
  • physical damage
  • unsupported file system
  • prolonged usage of the memory card

If you are looking for solutions to corrupted SD card problems, you can refer to the following link to learn some fleshed-out methods.

Basic Methods

Method 1: Make Sure the Memory Card Is Not Physically Damaged

Before using other methods, you should check out whether the memory card is physically damaged. They are known for being portable and convenient, but the edges inevitably increase vulnerability. Although some quality memory cards are usually designed to be tough and capable of weathering intense physical shocks, they are still so small that physical damage to them is hard to spot. Below are some common physical problems and how to tackle them respectively.

  • Water damage

Like many other electronic devices, memory cards are susceptible to water damage. Though some of them are touted as waterproof products, overlong saturation of a memory card can definitely lead to errors. If your memory card is wet, you can dehydrate it using a dry static-free cloth and then put it in place with dry air. If you have a dehumidifier, you can place the memory card near it for about 24 hours.

Important: Don’t put the memory directly under sunlight lest the high temperature should damage it.
  • Accidental drops

If the memory card has gone through accidental drops, it could suffer from physical damage. And in most cases, due to their sizes, it’s hard to spot and there isn’t much you can do. Check out the metal connectors and clean dirt on them. Tight it up if there is something loose.

  • Electrical surge

A sudden increase in the amount of electricity could overwhelm the circuity inside the memory card and hamstring it. Again, there isn’t much you can do. You can try to ground the memory card by touching its metal connectors with another metal object, like a mental bench.

Method 2: Ensure the Memory Card Is Correctly Inserted

Carefully remove the memory card from the device and then insert it in the correct orientation. If that’s the cause of the error, it can be immediately solved.

Method 3: Make Sure the Memory Card Is Approved

As we have mentioned, the problem may result from incompatibility between the memory card and the device. You can go to the camera manufacturer’s website to check whether the device supports the memory card.
