What is SD card memory card
Before we go into a problem about the causes and look for solutions for a damaged or unreadable SD card, it’s good to know what an SD card is. SD or secure digital is a digital Flash memory card format that is often used and is definitely used in portable devices such as PDAs in digital cameras or mobile phones.
This SD card was developed by several companies such as SanDisk Toshiba and Panasonic. In its journey and development of SD cards, there are also various famous shapes and sizes, namely mini SD and also micro SD. is a device that is often used in the latest Smartphones or cellphones.
Unreadable SD card cause
There are so many things that can cause the SD card embedded in a smartphone to be unreadable. This can happen suddenly or when you are doing activities on a smartphone. Here we summarize some of the common causes that often occur and cause your SD card to not read properly.
Micro SD card often switch devices
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.
Incorrectly way to removing the micro SD card
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.
The presence of Malware or viruses on the operating system you are using
Maybe this is one of the things that happens quite often to ordinary people who don’t know that the operating system has a virus that causes the SD card to become unreadable. In general, this malware or virus works to do something reading data continuously and when this happens then the smartphone you are using will work up to three times harder to do the job of reading data.
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.
Using the wrong device charger
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. This electricity requirement is to encourage the micro SD card to read and write properly without being disturbed.
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.
Device working too hard causing Micro card to be unread
Perhaps this is also the main cause of damage to the SD card. The cause of the SD card is damage if we make heavy tweaks or make excessive modifications to the operating system that makes this system work beyond the maximum limit given by the phone maker. Because some people also like to make changes to the standard operating system to produce better performance or appearance. 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.
Poor-quality Micro Card
There are so many brands or manufacturers of SD card makers today. Of the many micro SD card makers, there are also many counterfeit products that cause this SD card to be unreadable on your cellphone or cellphone. So don’t be too tempted by the cheap price of a well-known product because it is also usually a fake micro SD product which of course has poor quality.
