How to format a memory card as internal memory Xiaomi Redmi

Xiaomi and Redmi smartphone owners often face a shortage of space, especially in budget models where basic storage capacity is limited. Android offers an elegant solution called Adoptable Storage, which turns a regular microSD card into a full-fledged extension of the device’s internal memory. This allows you to install applications, games and save data directly to the flash card, bypassing system limitations.

However, smartphone makers, including Xiaomi, often hide this feature in the standard menu, preferring to use it. SD-The card is only a portable storage for photos and music, and to enable the card to be formatted as internal memory, the user will need to perform a number of specific actions and sometimes use third-party software. Formatting will completely clear the media, so it is important to back up all important files in advance.

In this guide, we’ll take a closer look at all the available Adoptable Storage activation methods on Redmi Note, Redmi, and Mi devices. You’ll learn about the risks associated with memory card speed and understand why this method may be the only way to comfortably use a smartphone with a small amount of built-in storage.

Preparation of memory card and device for formatting

Before starting the procedure, you need to make sure that your memory card meets the requirements of the system. SD-The card must have a high speed class, preferably a Class 10 or higher, and a standard UHS-I. Using slow cards will lead to serious interface delays and long application loads, as the system will constantly access them.

Make sure to remove the card from the device and connect it to your computer to copy all the important data to your hard drive or cloud storage. The formatting process we will run will irreversibly destroy all the information on the media. Also make sure that your Xiaomi smartphone battery is at least 50%, to avoid emergency shutdown at a critical moment.

⚠️ Note: Once formatted as internal memory, the card will be encrypted and linked exclusively to this smartphone, inserting it into another phone or computer and reading the data without resetting will not work.

Check that your Redmi model is compatible with memory extension. While most Android 6.0 and higher devices technically support this option, the MIUI or HyperOS shell can block access to it at the software level, in which case the standard menu tools will not be used.

Attempt activation through the standard settings menu

The first step should always be to check the standard functionality of the system, as in some regions or on certain versions of the MIUI firmware, this option can be available without unnecessary manipulation. To do this, insert the memory card into the slot and wait for the notification of the new drive. Click on the notification or go to the Settings menu → About phone → Storage.

In the list of storage devices, select your SD-If you're lucky, you'll see a three-dot menu in the upper right corner or a "Storage settings" button, which should have the option "Format as internal storage" or "Use as internal memory." If such a point is, the system itself will offer to format the map.

If the menu contains only the options “Clean” or “Format” (without mentioning internal memory), then the manufacturer has hidden this feature. Do not try to use third-party apps from the Play Market that promise to activate this feature without root rights – in 99% of cases on modern versions of Android they do not work, since system restrictions are deeper than the level of user applications.

• 📱 Go to Settings. → Warehouse and select SD-map.
• 🔍 Look for a three-point menu or a gear drive settings.
• ⚙️ Check for the item “Format as internal storage».
• 🔄 If the item is not, the standard method will not work, you need to ADB.

Using ADB to force the inclusion of a function

If the standard menu doesn’t offer the right option, the only working way is to use the ADB (Android Debug Bridge) debugging bridge, which does not require root rights, but requires a computer (Windows, macOS or Linux) and a USB cable.

To start, you need to activate the developer mode on the Redmi smartphone. → About the phone and quickly press 7 times on the item "Version" MIUI». After the message “You became a developer” appears, go to Additional → For developers and turn on the switchboard "Debugging by" USB». When connecting to a PC, confirm the request for debugging permission on the smartphone screen.

adb shell pm setForceEnableAdoptableStorage true

After entering this command in the command line of the computer (being in the folder with the ADB) Now, you go back to the storage settings on your phone. SD-If you re-connect the card, you should be able to choose the formatting type. Select "Internal Storage" and wait until the process is complete.

⚠️ Attention: Team ADB It doesn’t work on all versions. MIUI. In some cases, especially on global firmware in recent years, even this method can be blocked at the core level of the system.

Comparison of memory expansion methods on Xiaomi

There are several approaches to solving space shortages, and each has its own technical features, and it is important for users to understand the difference between simply transferring files, formatting through ADB, and using virtual memory to choose the best option for their Redmi model.

Below is a table that will help you compare the main characteristics of different methods of working with external drives on Xiaomi devices.

As you can see from the table, Adoptable Storage is the most radical, but also the most effective method for installing heavy games and applications. However, it imposes strict requirements on the quality of the memory card. Virtual memory, in turn, uses part of the built-in storage to expand RAM, which does not solve the problem of lack of space for files, but improves multitasking.

💡

Use SanDisk’s Extreme Pro memory cards or similar flagship models from Samsung. Saving the speed class of the card when using it as system memory will lead to constant hanging of the smartphone.

Data portability and application management

After successfully formatting the card as internal memory, Android will automatically start using the new space, but the old apps will remain on the built-in drive until you explicitly instruct the system to move them. → Annexes → All applications.

Select the desired application from the list. If the application supports portability, you will see a "Change" or "Move" button in the "Storage" section. SD-The system will copy the application files and data to a new medium, freeing up space in the phone's internal memory.

It’s worth noting that not all apps allow porting to an external drive. Developers can prohibit this from the application manifest for security or performance reasons. In such cases, the move button will be inactive or absent, and you will have to put up with the application taking up space in the built-in storage.

• 📂 Go to the settings of a specific application.
• 🚚 Click the "Change" button in the storage section.
• 💾 Choose. SD-data-transfer and cache.
• ⏳ Wait for the file copying process to be completed.

Camera and gallery MIUI You should also automatically switch to saving photos and videos to new internal memory (previously, the same thing is true). SD-Check the camera settings to make sure the save path is changed, which will allow you to shoot high-resolution video. 4K without the risk of overflowing the main section.

Possible problems and ways to solve them

There are some specific errors that can occur when you're using a smartphone with a formatted card. One of the most common problems is the message «SD-The card is corrupted" or "Formatting required" is often an indication that the card file system could not withstand the intense recording loads that are typical for internal memory.

Another problem may be slowing down the interface, and if you notice that the phone is slowing down after you embed the card, try reducing the number of widgets on your desktop or migrating back the heaviest system applications, and in critical cases, you may need to replace the card with a faster model.

⚠️ Note: If your smartphone stops seeing the card or constantly produces reading errors, don’t try to format it again right away. First try reading data through the card reader on your PC, as the card may have physically failed.

Users may also experience a situation where, after updating the MIUI or HyperOS firmware, the storage settings are reset, in which case the activation procedure via ADB may need to be repeated. Always have the current version of the ADB drivers and instructions for quick reactivation of the function at hand.

💡

Stability of the smartphone with SD-The quality of the card is directly dependent on the card's internal memory mode. Cheap drives quickly degrade when you actively write system files.
