How to make an SD card internal memory on Xiaomi Redmi 8

Owners of budget and mid-budget smartphones often face a lack of free space for installing new applications or downloading multimedia. Xiaomi Redmi 8, despite its popularity, can quickly exhaust the standard storage volume, especially if the user actively uses messengers and navigators. Adoptable Storage allows you to turn an external drive into a full extension of the system partition, which solves the problem of overflow.

However, it should be understood that the standard MIUI interface does not always offer this option explicitly. Successful storage combinations require a number of specific actions, including working with debugging menus and system commands.

Before you start technical manipulation, you need to assess the risks and prepare the device. Incorrect extraction of the card after insertion into the system can lead to malfunctioning of applications whose data was moved. Make sure that your card reader is stable and the flash drive has a sufficient write speed.

Preparation of equipment and choice of storage device

The quality and performance of the selected memory card directly affect the stability of the operating system after integration. Using slow or cheap models can lead to noticeable "freezes" of the interface and long run of programs. For Redmi 8, it is recommended to use UHS-I-class 10 or higher drives.

Make sure to back up all the important files on the flash drive, as the formatting process will destroy the entire data structure. USB-card reader to connect to the computer during the initial check, which will make sure that there are no broken sectors before starting to work with the smartphone.

Insert the card into the device slot and wait for the system to determine the drive. If the smartphone offers to choose the mode of operation (media files or internal memory), while ignoring this, as the standard method often does not activate the desired mode completely.

💡

Use cards ranging from 32GB to 128GB for optimal performance on the Redmi 8, as too large volumes can be handled more slowly by the built-in controller.

Activation of the developer mode and debugging via USB

To access the hidden memory management functions, you need to activate the engineering menu. Go to your smartphone settings and find the About section. Here you need to quickly click on MIUI version seven times until you notice that you have become a developer.

Then, the new option, "Advanced Settings" or "Advanced" will appear in the main settings menu. Go to it and select "Developers For", find the "Debug USB" switch and activate it by confirming action in the security dialog box.

In the same menu, it is recommended to find the "Do not turn off the screen" item and turn it on so that the display does not go out during execution of commands. It is also worth checking whether the "Factory Unlock" option is enabled, although this procedure may not require it if the bootloader is already unlocked or not necessary for ADB.

Using ADB for Forced Formatting

Since the "Use as internal storage" button may not be on the menu, we will apply the console command via your computer. You will need to install Xiaomi drivers on your PC and a minimum set of ADB tools. Connect your smartphone with a cable to your computer in file transfer mode.

Open the command prompt or terminal on your computer in the ADB folder and enter the connection check command. The device must request debugging permission, which must be confirmed on the smartphone screen.

adb devices

Once the serial number of the device has been successfully displayed, you can proceed to find the card ID. Enter the command to output the list of disks:

adb shell sm list-disks

In the answer, you'll see a string like disk:179.64 or something like that. Remember this ID, it's going to be used for the next step, and that ID is what kind of physical drive you want to convert to.

Formatting and combining sections

Now you have to execute a command that compels the system to format the card and create an encrypted partition on it, and be careful, after that, the card will become unreadable on other devices without unlocking.

adb shell sm partition disk:XXX private

Instead of XXX, substitute the ID you got in the previous step, and the system will format, which can take a few minutes, and you can't turn off the cable or take out the card.

Once the process is complete, notifications will show that the drive is ready, and now the card works as part of the internal memory, and you can transfer applications to it through settings, although the system files will remain on the built-in chip.

💡

Partition Disk:XX Private completely rebuilds the file system of the map, making it an integral part of Android without losing application data.

Data portability and application management

Once the map is successfully implemented, Android will begin to automatically distribute the load, but for maximum effect, it is recommended to manually transfer heavy applications. Go to the settings, select "Apps" and find the desired program.

If the "Storage" section is active, there's a "Change" button. Press it and select it. SD-Not all apps support this feature, as developers can prohibit the movement of their products.

For media files such as photos and videos, the system may also suggest clearing the internal memory. In the storage settings, you can see detailed location statistics. Check this section regularly to monitor the filling of new volume.

• 📸 The camera and gallery can automatically save new pictures to an external drive if allowed in their settings.
• 🎵 Music and podcasts often search for files on internal memory by default, so their paths will have to be changed manually.
• 📂 File managers can help you move old folders with documents to a new volume without losing structure.

Possible problems and ways to solve them

During operation, there may be situations when the system stops seeing the card or applications crash, often due to a slot contact violation or software failure after the MIUI update.

If the card appears to be corrupted, try restarting the device. In the worst case, you will need to re-format it, which will result in loss of data on the flash drive. Always have a backup of important documents at hand.

Slowing down the interface is another common symptom, which occurs when the card reads slower than the phone's internal memory, and then it makes sense to put the card back in portable storage mode.

⚠️ Warning: Removing the card without first disabling in the settings ("Unmount") will lead to the collapse of applications whose data is on the flash drive, and possible loss of progress in games.

⚠️ Attention: When resetting the smartphone to factory settings, data on SD-The card formatted as internal memory will be encrypted and inaccessible without the key stored in the phone system.

Comparison of storage modes

Understanding the difference between standard mode and internal memory mode helps avoid errors. The table below shows the key differences that Redmi 8 owners need to consider.

When choosing a mode, weigh the need to expand the system partition against the risk of data loss. For most users, the best option is to store media on a map, and applications on an embedded chip.

💡

If you are planning to sell the phone, be sure to format the card into portable media mode or retrieve it before resetting so that new owners do not get access to your encrypted data.
