Many Xiaomi smartphone users are facing a lack of built-in storage and use the Adoptable Storage feature, which allows you to turn a regular microSD card into an extension of system memory. SD-The cards are often slower than the speed of the built-in flash drive, which can lead to slowing down the interface and long downloads of applications.
The decision to return the card to removable media requires careful attention, as the process involves the complete removal of all information. You need to understand that shutting down internal memory is impossible without prior formatting, which will destroy all files, photos and installed applications. In this article, we will discuss in detail all the steps of the procedure, risks and alternative methods of space optimization.
Before you start, make sure you back up important documents.The process of changing the type of memory on Android is irreversible in the context of data retention.Let's take a look at why users often abandon this feature and how to properly prepare the device for changes.
Why you should stop using SD as internal memory
Using a memory card as a system storage is a trade-off that is made to save space, but it is rarely durable. The main problem is the physical difference in write and read speeds between an embedded eMMC/UFS module and budget or even medium-sized microSD drives. The system starts writing app cache and temporary files to a slow card, causing noticeable lags.
⚠️ Attention: When in use SD-It's encrypted with a unique key of a particular smartphone, and you can't just move it to another phone or computer and read it without completely resetting the card.
Another critical factor is the rewrite resource. Memory cards are not designed for the constant intense work that the MIUI or HyperOS operating system requires. Frequent log writing, cache and updates quickly wear out memory cells, leading to sudden read errors or complete loss of the drive.
If you notice that the phone started to work slower after activating this feature, or if the memory card suddenly stopped being identified, the only surefire solution is to return to standard mode, which will restore stability to the system, although it will require manual file management in the future.
Device preparation and data backup
Before you change the storage configuration, you need to do a thorough preparation. Since formatting will destroy all data, you need to copy photos, videos, documents and music to your computer or to the cloud. Xiaomi's built-in tools allow you to do this through Settings → About Phone → Backup and Restore.
Pay special attention to the list of installed applications. If you turn off the internal memory function, all programs transferred to the map will be deleted. You will have to re-download them from Google Play or GetApps. It is recommended to make a list of important applications or take screenshots of the desktop.
☑️ Preparation for shutdown SD-map
Also, be sure to check for the current firmware version. Sometimes bugs in older versions of MIUI can prevent the drive from formatting correctly. Go to Settings → About Phone → MIUI version and make sure the system is updated to the latest available version.
Instructions: How to disable SD card from internal memory
The process of returning the card to portable storage mode is performed through the standard Android settings menu. the interface may vary slightly depending on the shell version, but the logic of actions remains the same for all Xiaomi, Redmi and Poco devices.
Follow a step-by-step algorithm to avoid errors. Do not interrupt the process by pressing navigation buttons or locking the screen, as this can damage the file system.
- Open the Settings menu of your smartphone.
- Go to About Phone or immediately look for Warehouse (in new versions it may be called Memory).
- Find yours on the list. SD-It's usually displayed separately from the internal memory.
- Click on the map to open the control menu, then select Storage Settings or three dots in the corner of the screen.
- In the menu that opens, select Format as a portable storage (or Use as a portable storage).
⚠️ Note: If the formatting point is inactive or hidden, it is possible that the card is damaged or occupied by system processes.
Once you have selected a command, the system will issue a warning that all data will be deleted. Confirm the action by clicking Format. The process will take from a few seconds to a couple of minutes depending on the size of the card, and when completed, the phone will notify you of the successful mode switch.
What to do if there is no formatting point?
Table of comparison of modes of operation of SD-card
To better understand the difference between the two drive modes, let’s look at their main features in a comparative table, which will help you make an informed decision about whether to use the card again as internal memory in the future.
| Characteristics | Internal Memory (Adoptable) | Portable storage |
|---|---|---|
| Encryption | Yeah (device binding) | No (works on any device) |
| Speed of operation | Depends on the speed of the card (often slow) | Standard for multimedia |
| Installation of applications | Automatically on the map | Manually only (not all applications) |
| Risk of data loss | High when your phone breaks | Low (data available on PC) |
| Impact on the system | May slow down the OS | Minimum impact |
As you can see from the table, portable storage mode is more versatile and secure for your data, it makes it easy to transfer files between devices and does not create a critical dependence on a particular instance of a smartphone.

Possible errors and ways to eliminate them
While formatting or operating a card in internal memory, Xiaomi users may encounter various system errors"SD-Card damaged or persistent notifications of formatting even after successful procedure.
Often the reason lies in the file system. Android requires ext4 or f2fs to work as internal memory, whereas portable mode usually uses FAT32 or exFAT. If a switching malfunctions, the partition structure may have broken.
To eliminate errors, try the following algorithm:
- 🔄 Reboot: Banal switching off and on the smartphone often resets memory controller errors.
- 🛠 Error Check: In the store menu, find the "Check" or "Fix Errors" option if available.
- 💾 Full formatting: If data is not important, select Clear All in the map settings to create a new partition table from scratch.
⚠️ Warning: If the phone boots cyclically after installing the card, remove it immediately.The problem may be physical damage to the drive, which shortens contacts or causes driver conflict.
Alternative ways to expand memory on Xiaomi
If the refusal of use SD-As internal memory has led to a shortage of space, don't rush to remove important applications. There are several effective ways to optimize the space without compromises in the speed of the system.
The first and most effective method is using cloud services: Google Photos, Yandex.Disk or Xiaomi Cloud allows you to store media files online, leaving only thumbnails on the device, which frees up gigabytes of space instantly.
💡
Regular cleaning of the Download folder and the messenger cache (Telegram, WhatsApp) can free up to 10-15 GB of space without removing important applications.
Also worth paying attention to the function "Virtual memory" (Memory Extension), available in new versions of HyperOS and other versions of the system. MIUI 14.It allows you to use part of the free space of the main memory to expand RAM, which has a positive effect on multitasking, as opposed to slow. SD-map.
