The message “Storage is damaged, your device is at risk” on Xiaomi smartphones (including the Redmi, POCO and Black Shark models) is one of the most frightening system errors that appear suddenly when you boot a device, after a MIUI update, or even during normal operation. Unlike typical memory shortage notifications, this warning signals critical failures in the file system that can lead to data loss, the inability to boot the OS or even “brick” the gadget.
The problem is common for Android 10-14 devices with MIUI 12-14 firmware, but it is especially common for models with eMMC memory (e.g. Redmi Note 8/9, POCO X3) or cheap modifications with low-quality storage chips. 80% of the time, the error is not due to viruses (as many people think), but to hardware memory defects or software conflicts after incorrect updates.
In this article, we will discuss:
- 🔍 Exact causes of error (from partition damage) /data memory-wearing).
- ⚠️ How dangerous it is to ignore the warning (risk of loss) IMEI, bootloop.).
- 🛠️ 4 working ways of fixing - from reset to flashing through Fastboot.
- 📱 Specifics for different models (Redmi, POCO, Mi).
1.Why does the error "Storage damaged" appear?
A warning works when MIUI detects inconsistencies in the file system structure, and it can be caused by several factors, and it is important to distinguish them, and the method of solving depends on it.
Main reasons:
- 💥 Hardware wear of memory: Chips eMMC/UFS They have a limited resource of records (especially in budget models). 3–5 During the years of intensive use, memory cells begin to “drop” which leads to read/write errors.
- 🔄 Failed update MIUI: If the firmware is interrupted (for example, due to battery discharge) or a “curve” of the assembly was installed, system partitions are damaged (/system, /vendor).
- 🦠 Viruses or root interventions: Rarely, but some malicious applications (or incorrect actions after getting root) can damage the partition table.
- ⚡ Sudden power outage: If the device is turned off during data recording (for example, when shooting a video) 4K), The file system may remain in an unstable state.
On models with eMMC 5.1 (e.g. Redmi 9A, POCO C3), the error often occurs due to the degradation of the memory controller, in which case even resetting the settings will not help - you need to replace the chip.

2.How dangerous is it to ignore a mistake?
Many people just click Cancel and keep using their phone, but there's a serious risk of that.
- 📵 Loss of loss IMEI: Damage to section /nvram (where the serial numbers of the communication modules are stored will cause the network to disappear. IMEI on some models (Redmi Note) 7 You can only use Engineer Mode.
- 🔄 Bootloop: The device will be constantly restarted without reaching the lock screen. /boot or /recovery.
- 🗃️ Data loss: Photos, contacts, and messages may become unavailable if a partition is damaged. /userdata. Recovering them without a backup is almost impossible.
- 💀 «Brick: In the worst case scenario, the phone will stop turning on completely (black screen, no button response). EDL Mode with Boxing (UFi, EasyJTAG).
⚠️ Warning: Unlocked Bootloader devices have a 3x higher risk of bricking. If you see an error after installing custom firmware, return to stock immediately. MIUI via Fastboot.
Method 1: Soft reset (without loss of data)
If the error is first time and the phone is still working, try restarting the file system without deleting user data, a method that helps in 30-40% of cases where the problem is caused by a temporary failure.
Instructions:
- Open the Settings. → The phone.
- 7 times tap on the item "Version" MIUI» (This will turn on the developer mode).
- Return to the main settings menu and select “Advanced” → “Developers”.
- Find the option “File System Check” (or “Fsck”) and click “Do Check”.
- After the reboot, check if the message has disappeared.
If this method does not work, move on to more radical measures.
☑️ Preparation for resetting settings
4. Method 2: Hard reset via Recovery
Resetting to factory settings (Wipe Data) deletes all user data, but restores the integrity of system partitions, a method that is effective if the error is caused by a software failure rather than hardware damage to memory.
Step-by-step:
- Turn off the phone.
- Press Volume Up + Power before the Mi logo appears (this is Recovery Mode).
- Select the language (volume buttons) and tap "Wipe Data" → "Wipe All Data".
- Confirm the action by entering a password (if it was set).
- After reset, select “Reboot” → “Reboot to System”.
If the error persists after the reset, then the problem is deeper - the memory chip itself or system partitions are damaged, in which case only the firmware will help.
⚠️ Note: On some models (POCO F1, Mi 8) After the reset, the section may disappear /persist, If the gyroscope or camera stops working after the reboot, you will need to manually restore this partition via Fastboot.
5. Method 3: Fastboot Fastboot Fastboot Fastboot Fastboot (for Advanced)
If soft and hard resets don't work, you have to completely reflash through Fastboot, which restores all system partitions, but requires a PC and commands.
What you need:
- 🖥️ Computer with installed Xiaomi drivers (official website).
- 🔌 Cable USB Type-C (original, undamaged).
- 📦 Fastboot firmware ROM For your model (you can download Xiaomi Firmware Updater).
- 🛠️ Mi Flash Tool (version 2023)+).
Instructions:
- Unpack the firmware in a folder without Cyrillic characters (for example, C:\MIUI\fastboot_rom).
- Turn off the phone and press Volume Down + Power to enter the Fastboot (a rabbit will appear with the inscription Fastboot).
- Connect the device to your PC and start the Mi Flash Tool.
- In the program, click "Select" and specify the path to the folder with the firmware.
- Select the “Clean All” mode and click “Flash”.
- Wait for the end (10-15 minutes) and the phone will reboot automatically.
If the phone doesn’t turn on or hangs on the Mi logo after firmware, the bootloader is damaged, in which case the firmware is required via EDL Mode (for power users or service centers only).
💡
Before you install the firmware, disable the antivirus – it can block Mi Flash Tool files as “suspicious.”
6. Method 4: Replace the memory chip (if nothing worked)
If all software methods have been tried and the error persists, the reason is almost certainly hardware wear and tear, in which case only replacing the eMMC/UFS chip will help.
Signs of hardware damage:
- The error occurs even after full firmware.
- The phone is spontaneously rebooted.
- Applications “fly out” with the error “The application has stopped”.
- Storage displays the wrong amount of memory (for example, 64 GB instead of 128 GB).
Cost of repair:
| Model | Type of memory | Cost of replacement (₽) | Difficulty |
|---|---|---|---|
| Redmi Note 8/9 | eMMC 5.1 | 2 500–4 000 | Medium |
| POCO X3/X3 Pro | UFS 2.1 | 3 500–5 500 | Tall. |
| Mi 11/12 | UFS 3.1 | 5 000–8 000 | Very high. |
| Black Shark 4/5 | UFS 3.1 + SSD | 7 000–12 000 | Expert level |
Replacement of memory is better to entrust the service center - self-repair without experience and soldering station almost always ends in damage to the motherboard.
💡
If your Xiaomi is guaranteed, do not try to sew or disassemble it yourself! Contact the official service - repair warranty will cost free (provided that the damage is not your fault).
7.How can you prevent the error from recurring?
To minimize the risk of storage damage, follow these guidelines:
- 🔋 Don’t let the power drop below 10%: Sudden power outages during data recording are one of the main causes of failures.
- 📥 Update. MIUI Wi-Fi only: Interrupted download OTA-The package can damage system files.
- 🚫 Avoid memory cleaners: Apps like Clean Master or DU Speed Booster often deletes important cache files, which leads to errors.
- 🔄 Regularly reboot your phone: Long-term work without a reboot accumulates errors in the file system.
- 📁 Don’t store important data on your phone: Use cloud services (Google Drive, Mi Cloud) or physical copies on your PC.
For eMMC models (e.g. Redmi 7/8/9), it is particularly important to limit the number of write cycles. Turn off automatic optimization in Settings → Battery → Optimization and avoid frequent use of memory-intensive features (e.g., 4K video recording).
