1. Uninitialized card

‘Card not initialized’ is one of the common video memory card error messages that pop up the screen due to various reasons. Following is the list of reasons behind this error message.

  • Inappropriate electrical connections
  • Fragmentation of the files after data being instantly written or erased
  • When the memory card is new and directly used in the device, then due to format differences, it can show up ‘Card not initialized’ error message

This error message when appears on the screen makes it difficult to access the data stored on the video memory card and in worst-case scenarios cause the file corruption.

2. The card cannot be used

‘The card cannot be used’ is an error associated with the video memory card and may result in video file corruption on the device. This error message appears on the screen due to the following reasons:

  • Inappropriate removal/ejection of the memory card from the device can cause the error and leads to data corruption. To avoid any consequence, you should always go for the proper ejection method for a memory card to protect the integrity of data.
  • Improperly switching off the device when it is connected to the memory card. It can be due to power failure or irregular power connection. This can cause data corruption stored in the memory card.
  • The low battery of the device connected to the video memory card can also cause this error. Transferring the data or downloading it directly to the memory card when your device is warning you about the low battery causes file corruption and also harms the data already stored on the memory card.
  • Virus and malware threats can impose a high risk of ‘The card cannot be used’ error message. It leashes to the memory card and makes the data corrupted and then inaccessible. A strong anti-virus can eliminate the chances of an error message.
  • The error can also appear when the video memory card is used for multiple devices. It is ejected and injected several times in various devices and this causes data and memory card corruption.

3. The card is not formatted

Due to the improper ejection method used for the video memory card, the error message appears on the screen that says i.e. ‘The card is not formatted’. This makes data inaccessible on the memory card and the only solution left is to format the memory that in turn means losing all the data.

4. Write error

As a common practice, some video memory cards come with a switch which is when turned on, you can write the data on the memory card. I an attempt to write the data, you can see an error message on the screen that shows the card is write-protected. If the card fails to unlock the write data on the card option, the only way left is to format the card that would result in the loss of precious data.

5. Read error

Using a card reader on the device to read data on the memory card is the common practice. But sometimes, an error message appears as ‘card cannot be read by your PC’. This is the read error. In short, data is inaccessible in this case. Mostly it occurs due to a faulty device or by using the outdated drivers.

As a result of these errors, you no longer can access any files present on the memory card. While this appears to be a dead-end, there actually are a few things that we may do in order to restore the contents of the broken or corrupted memory card. There are several different techniques that may be deployed in this regard but the best possible solution is to make use of some data recovery software application to get all your lost data back.
