Moving with the SD card too often from 1 device or smartphone to another device will have a risk for the SD card to be damaged and then unable to read data properly. The Micro SD card has a vulnerability if this card is often moved on the device because Every time a transfer occurs the micro SD card must adapt to the existing operating system or the power consumption given to the card reading. Because each device has different specifications, you should not move the SD card too often or remove it from the card housing. We recommend that you use a data cable to transfer micro SD data to another device.

This is one of the things that most often happens to devices that have a micro SD card slot on the side or are easy to access without turning off the cellphone or cellphone. On old devices, we often find the SD card placement on the side of the device. Ease of access This is what makes people often plug in and out without realizing that it can cause permanent damage to the micro SD card.

And this is the reason why the latest smartphone makers have given the system the option to safely remove the SD card. Even though this feature is built into the operating system, we recommend that you don’t always do this because it will cause the SD card to not read properly if you install and uninstall it too often. And if indeed you are forced to do it as much as possible you have to turn off the smartphone or device you are using and it would be better if you use a data cable for data transfer.

In general, this micro SD card has a limit for reading and writing data at a certain level and due to a virus or malware, finally reading this data is done by exceeding the capacity given to this micro SD card which can cause this card to be unreadable. well.

Often we unconsciously use a charger that is not the default. This can also result in reading your micro SD card not working properly. As additional external storage memory, the SD card also requires a stable electric current.

And if you are there when charging, you don’t use the original charger or according to the capacity of the cellphone you are using, it is likely that the incoming power from the charger or charge you are using is more than what can be received by cellphone or smartphone. This causes excess electricity to enter the SD card and then causes heat which also makes the SD card unreadable.

Perhaps today’s smartphones have smart technology to intelligently read which components can receive overvoltage or power and which components cannot. This smart technology is able to adjust how much power can be accepted or rejected. Even so, it’s a good idea maybe you can use the default charger from a smartphone or cellphone so that the device you use lasts longer.

The system changes of the phone you are using also affect the micro SD card in the phone. Because this external storage media will also follow changes that occur in the operating system.

In general, anything that is done excessively will also cause the device to work harder. For example, when we save a high-resolution video that requires good read and write speed on the SD card, the micro SD card shell that we embed has a low read and write speed, this can also cause the SD card to suddenly become unreadable.
