How to combine phone and memory cards Xiaomi Redmi Note 8 T

Owners of the popular Xiaomi Redmi Note 8 T smartphone often face a lack of free space to install new apps and games. Despite the fact that the device supports microSD cards, by default, the Android operating system does not allow them to be used as a full-fledged extension of internal memory. This limitation creates a situation where the system partition is full, and gigabytes on the USB drive remain unavailable for programs.

There is a technical possibility to bypass this limitation and force storage to be combined by turning a memory card into part of the system partition, a process known as Adoptable Storage that requires careful attention and an understanding of the risks, as interference with partition structure can affect the stability of the gadget. In this article, we will discuss in detail all the stages of preparation and execution of the procedure.

It is important to understand that once combined, the data on the map will become unreadable on other devices without special formatting. SD-So backing up your phone is a must-have first step before you start any manipulation, and if you're willing to experiment, you can significantly expand the functionality of your smartphone.

Features of memory in MIUI and the limitations of Android

The Android operating system that underpins the MIUI shell on the Redmi Note 8 T was originally designed to be split into internal storage and external storage. Internal memory has high read and write speeds, which are critical for operating systems and heavy applications. Memory cards, even high-speed ones, are often inferior in performance to embedded memory chips, which can slow down the device when used actively.

Xiaomi, like many other manufacturers, hides memory integration by default in the standard settings menu, to prevent user errors and ensure the stability of the interface, but for advanced users, it is possible to activate hidden functions through USB debugging and special commands.

⚠️ Note: Using low-quality memory cards (speed class below 10) after combining can lead to severe interface lags and application freezes.

It should also be noted that not all applications support installation on external drives. Software developers may prohibit the transfer of their products to external drives. SD-However, system files, cache and some user data can be moved, freeing up valuable space.

• 📉 Standard memory card runs slower than built-in storage NAND.
• 🔒 MIUI Blocks direct association through the graphical settings interface.
• ⚙️ Activation requires the activation of the developer mode and use ADB.

Preparation of equipment and software

Before starting the procedure, you need to make sure that you have all the necessary tools. You will need the Xiaomi Redmi Note 8 T smartphone itself, a high-quality microSD memory card (preferably from 32 GB and speed class). UHS-I or higher) and a computer running Windows, macOS or Linux. USB-cable capable of transmitting data, not just charging the device.

You need to install Android device drivers and Platform Tools (ADB and Fastboot) to your computer, which lets you send commands directly to your phone’s operating system, and without ADB, you can’t execute a command to create partitions on your memory card.

Make sure to make a full backup of important data. During the setup process, the memory card will be formatted, and all photos, videos and documents stored on it will be permanently lost.

Make sure your smartphone has USB debugging enabled. Go to Settings → About Phone and quickly click on MIUI Version seven times until you have become a developer. Then, in the Additional → For Developers menu, activate the USB Debugging Switch.

Activate Adoptable Storage through ADB

Once all the components are ready, you can start directly combining memory. Connect your smartphone to your computer with a cable. You'll see a request for debugging permission on your phone screen, confirm it. Open the command line or terminal on your computer in the folder with the ADB installed.

The first step is to check the connection. Type in the adb device command. If a device has been listed, the connection is correct. If the status is unauthorized, check the screen of the smartphone and allow access.

adb shell sm list-disks

This command will display a list of connected drives. The memory card will be displayed as disk:XXX,XX, where XXX,XX is the unique identifier of your flash drive. Write down this identifier, which you will need for the next command.

And then you run a partition command, and it turns the memory card into an encrypted storage that's only available to this phone, and the syntax of the command is as follows:

adb shell sm partition disk:XXX,XX private 100

Here private means private storage mode, and 100 indicates using 100% of the card size for applications. Once the command is executed, the phone can restart or a notification will appear on the screen about setting up a new storage.

⚠️ Note: If you specify an incorrect disk ID in the command, you can accidentally format the internal memory of the device, which will lead to complete data loss.

Comparison of data storage methods

Understanding the differences between memory card modes will help you make an informed decision: Standard mode involves using a flash drive only for media files, while Adoptable Storage mode integrates it into the system, each method has its advantages and disadvantages that are worth considering.

When you select private mode, the system automatically encrypts the data on the memory card, binding it to a particular device, which means that when you remove the card and install it in another phone or computer, the data will not be displayed.

If you plan to change memory cards frequently or use a single flash drive to transfer files between devices, the combined memory mode will not suit you, in which case it is better to limit yourself to transferring photos and music, leaving the system partitions intact.

💡

Use Extreme or Ultra memory cards from proven brands (Samsung, SanDisk, Kingston) to minimize the risk of lost performance after the combination.

Application management and data portability

Once the memory is successfully combined, the system begins to perceive the card as part of the internal drive, but the automatic transfer of all installed applications may not happen instantly.

Go to Settings → Applications → All applications. Select the desired application that takes up a lot of space. If the program supports portability, you will see a button called Memory or Storage, where you can select the option to change the storage location.

• 📲 System applications usually cannot be moved to SD-map.
• 💾 Heavy gaming often takes up more than 2GB and requires a transfer.
• 🔄 Cache of some applications (for example, maps or browsers) can be reconfigured to work with external memory.

Some users prefer to use the Force allow apps on external media feature, which is on the Developer Menu, and activating this option allows you to transfer even those applications whose developers have banned installation on external media. SD-map.

However, be careful: transferring critical system processes to a slow memory card can lead to unstable operation of the Redmi Note 8 T. If after transferring a particular application you notice frequent departures or freezes, return it to internal memory.

⚠️ Note: Do not remove the memory card while the phone is on if it is used as part of internal memory.This can cause file system error and application data loss.

💡

Memory integration is only effective when paired with high-speed memory cards; cheap drives can slow down the entire smartphone.

Possible problems and ways to solve them

A smartphone with combined memory can be a technical challenge, with users often reporting card damage or slow interfaces, which can be related to both physical wear and tear and software conflicts.

If the system stops seeing the apps installed on the card, try restarting the device. In rare cases, you need to re-perform the formatting procedure. It is also possible that the file system of the card has been damaged due to a sudden power outage.

You can use Android built-in tools or third-party snails to diagnose the state of the drive. Type in the ADB command line:

adb shell sm list-volumes

It will show the status of all storage volumes, and if the card is broken or missing, you'll need a physical contact check or a microSD replacement, and sometimes it helps to clean the card's contacts with soft cloth.

Remember, memory card rewrite is limited. When you use it in Adoptable Storage, it wears out faster than when you store it in a normal way, and you check the health of the memory card regularly and back up important data.
