Unreadable SD Card: Here's an Easy Way to Fix It

Infokekinian.com – Here is information about the unreadable SD Card: here's an easy way to fix it. Check out this article to the end to find out more complete and clear information.

One of the most important components of a smartphone is the SD card, also known as SD card and external memory.

The presence of this additional memory will certainly be beneficial, especially for handsets with limited internal storage (ROM) capacity.

Of course, external memory can assist users in storing additional data without burdening internal storage.

Some SD card manufacturers even offer the hard drive sizes we see on PCs and laptops, up to 2TB. There's a lot of information here.

However, users have reported some issues with this SD card, especially when using it with a large capacity.

So, in this article, we will show you how to misread an SD card in a few simple steps.

What is SD Card?

A Secure Digital card, or SD card, is a non-volatile data storage method for use in handheld computing devices.

Non-volatile means the SD card can store information even when the device is not receiving power.

They are typically used as "bridge media" that can store data and be transferred between different products.

Developed by high-tech companies such as Panasonic, SanDisk and Toshiba, they are commonly used as storage or memory cards for digital cameras, mp3 players, camcorders and notebook computers.

SD Card Memory Card Type

Along with the increasing need for increasingly large data storage, memory cards (memory cards) are now a basic need that cannot be separated.

Especially for local cellphones, which usually have minimal internal memory, a memory card is a mandatory item that must be there. Do you know?

It turns out that the memory cards on the market have different types and unique specifications that make them different from one another. The following are the different types and specifications:

1. Shape Memory Card

The following are several types of memory cards on the market:

1. SD Card is standard size, usually used for digital cameras or DSLRs but not used for cellphones or tablets considering the size of this memory card is quite large, around 32 x 24 x 2.1mm.

2. Mini SD, previously this type of memory was widely used in cellphones, for example in the Nokia N73 cell phone.

However, on the latest cellphones, this type of memory is no longer used. The size of the mini SD memory card is 21.5 x 20 x 1.4mm.

3. Micro SD, among the types of memory currently in circulation, micro SD memory is the most frequently used type.

This is because the size is quite small, around 15 x 11 x 1mm. With this size, this type of memory is widely used in cellphones, tablets and digital cameras.

2. Memory Card Specifications

Currently there are 3 types of SD memory cards in circulation, namely the types of SD, SDHC, SDXC. The main difference between the three types of memory lies in the data storage capacity:

1. Memory card type SD (secure digital) can only store data up to 2 GB.
2. Memory card type SDHC (Secure Digital.High Capacity) can hold up to 32 GB of data.
3. SDXD (Secure digital extended capacity) type memory cards can accommodate data ranging from 32 GB to 2 TB.

SDHC is the latest storage standard developed by the SD Card Association. The SD Card standard uses the FAT16 file format which supports up to 2GB of data capacity, while the SDHC memory card uses the FAT32 file format which has a data capacity of up to 32GB.

Meanwhile, SDXC memory cards are the next generation of SD memory cards. The SDXC memory card is the world's first storage device that meets the new specifications of version SD Card Memory 3.00.

Where the maximum speed for writing data (write) is up to 35MB/s and the read speed is up to 60MB/s.

3. Memory Card Speed

the speed level on the memory card is classified by codes in the form of numbers. Currently, non-UHS memory cards are divided into 4 different classes.

Meanwhile, UHS memory cards only consist of 1 speed class. Below are categories of memory card speeds:

1. Class 2 : 2MB/s write speed
2. Class 4 : 4MB/s write speed
3. Class 6 : 6MB/s write speed
4. Class 10 : write speed 10MB/s
5. UHS-1 : data write speed up to 10MB/s.

These numbers indicate the maximum speed of data transfer that can be achieved by the memory card.

How to Overcome Unreadable SD Card

Here's how to deal with it:

1. Clean the SD Card Brass

Even though it sounds simple, this method has proven to be effective. Dirt or dust will be very likely to stick to the external memory brass that we use.

Therefore, this is the first step that we really have to take to overcome an unreadable SD card.

How to clean it is quite easy, because you can use an eraser, tissue, cloth, or cotton.

Clean slowly and do it in the same direction so that the cleaning process is more effective.

2. Try on another smartphone

This second step is actually quite simple, because we only need to try it on another device first.

But make no mistake, because some smartphones are not compatible with some SD cards, or only support up to a certain size.

It doesn't hurt to try it on another device, because of course there is a possibility that the SD card you are using works.

3. Check SD Card Via Laptop

Apart from trying it on another smartphone, you can also check the SD card via a laptop by inserting it into the card reader.

This method is also fairly easy, but for those of you who don't have a card reader slot, you will need the help of a tool.

After inserting the SD card into the card reader, open My Computer, right-click on the SD Card, click Properties, select Tools, then press Check.

Wait for a while, because your laptop will check if there is an error on the SD card that you have.

4. Use a Different File Manager Application

Another easy way that you can do is to use the help of a different file manager application.

Believe it or not, but we have experienced an error when using the default file manager on a smartphone.

You should try this, considering that there are so many file manager applications available for you to use.

5. Incorrect SD Card Position

Apart from the several methods above, making sure the position of the SD card is installed correctly also affects you.

Even though it sounds trivial, by shifting the position of the SD card even a little bit, of course it will affect whether the SD card can be read or not.

Easily, you have to remove the card, and put it back in properly.

6. Try to fix it with the help of the application

If the previous method also doesn't work, maybe you can try to fix an unreadable SD card with the help of an application.

Based on information from the website itself, DiskInternals Uneraser is an application to fix unreadable SD cards, or errors.

Its use is fairly easy, because you only need to download this application first on your computer or laptop.

After that, you can insert the unreadable SD card with the help of a card reader. Run the application, and there will be several options to fix it.

7. Format SD Card

If all the methods above don't work, another way you can do is to format the SD card.

Formatting or deleting all data on the SD card is the last way that you can easily do.

Make sure the SD card is damaged first before doing this step, because deleted data cannot be recovered.

Conclusion

That's a little information on how to deal with unreadable SD cards, the presence of an SD card is certainly very helpful for smartphones with small internal storage.

With this additional memory, storing data in the form of photos, music, videos and documents will become much easier.

In addition, these memory cards can be used on different devices, making them more flexible to use.
