Shutdown USB-Xiaomi's smartphone drive seems like a simple operation, you take the flash drive out of the port, that's all. But this approach can damage the file system, lose unsaved data, or even crash the drive. MIUI) It caches the recording operations, and abruptly extracting the device can interrupt these processes. SSD-Data storage devices that require more time to synchronize data.
In this article, we will analyze the unique nuances for Xiaomi: why the standard method through notification does not always work, how to be with the company. OTG-And what if the system freezes when you try to shut down, and then you have a different version compatibility table. MIUI and a list of models where safe extraction is disabled by default.
Why you can’t just pull a flash drive out of Xiaomi
Unlike the iPhone or older versions of Android, where USB-drives mounted in the mode “read only”, modern Xiaomi smartphones (starting with the MIUI 12) support full recording to external devices:
- 📁 File system of the drive (usually) FAT32 or exFAT) may be damaged by sudden extraction.
- ⏱️ Recording operations (such as copying photos) are not completed instantly – the data first enters the buffer, and then is written to a flash drive.
- 🔌 Some of them OTG-Powered adapters create a 'hot connection', which increases the risk of failure.
In practice, this translates into:
- 🚨 Loss of last copied files (they disappear after retrieval).
- 💥 Converting a flash drive to a format RAW (formatting is required).
- 🔄 Hanging smartphone at the next connection of the same drive.
⚠️ Attention: On Xiaomi models 12/13 Pro with port USB-C 3.2 The data transfer speed is higher, and the record buffer is larger, and the risk of file damage from improper extraction increases by a factor of two. 40% Compared to the budget Redmi.
Official method: through the notification panel
The most obvious method is to use the "Safe Retrieval" button in the notification curtain, but it doesn't always work. Here's a step-by-step guide with MIUI in mind:
- Connect. USB-Smartphone storage (if necessary, use it) OTG-adapter).
- Wait for the notification to appear. USB-drive-in.
- Open the notification bar and find the item USB-The sleeve (in some cases, it is hidden under the).
- Slip on the notification and select Remove or Disable.
- The device can be safely removed (usually takes 2-5 seconds).
If the Remove button is inactive or absent:
- 🔄 Reconnect the drive (sometimes it helps to change the port to the port). OTG-adapter).
- 📱 Reboot your smartphone – it will reset the cache USB-module.
- 🛠️ Check the drive on another device (it may be damaged).
⚠️ Attention: On Xiaomi with MIUI 14 and later, the safe extract button may not appear if the drive is formatted in NTFS. The system considers it “incompatible” and mounts it in “read only” mode».

Alternative methods of shutdown
If the standard method didn't work, use one of these options, which are different in complexity and are suitable for different scenarios:
| Method | Suitable for | Advantages | Deficiencies |
|---|---|---|---|
| Through "Settings." | All Xiaomi models | It works even without notice. | It takes a few steps. |
| ADB-team | Advanced users | Instant shutdown | You need developer rights. |
| Reboot. | Accidents | Guaranteed to unmount the drive | Long and uncomfortable. |
| File manager | MIUI 12–14 | Visual control | Not always available. |
Let’s look at each method in more detail.
1. via the Settings menu
This method is universal and works on all versions of MIUI:
- Open Settings → Connections and Sharing → USB.
- Tap on the name of your drive (e.g. SanDisk Ultra 64GB).
- Choose Disable or Remove.
- Confirm the action.
If the paragraph USB Not available in the menu, try the path: Settings → Additionally. → Special facilities → Physical buttons → USB-accumulator.
2. ADB-team (for experienced)
If you have the developer mode enabled, you can unmount the drive via ADB:
adb shell sm unmount /mnt/media_rw/[ID_ driveTo find out ID_The storage device, pre-execute:
adb shell ls /mnt/media_rw/⚠️ Attention: Misuse of the right ADB It can cause a smartphone file system to crash. Don't experiment unless you're confident in the commands.
3.Rebooting the smartphone
The last method, if the drive "hangs" and does not turn off:
- Hold the power button until the off menu appears.
- Select Reboot.
- After turning on the smartphone, remove USB-accumulator.
This is guaranteed to unmount the device, but takes up to 2 minutes.
4. Through the file manager
In some versions of MIUI (e.g. 13.0.4), you can disable the drive directly from the Files app:
- Open the files. → USB-accumulator.
- Slip on the three-point menu in the upper right corner.
- Choose Extract.
💡
If the drive doesn’t shut down for more than 10 seconds, check it for viruses with Google Play Protect – some malware blocks unmounting.
Features for different Xiaomi models
Manufacturer makes changes to processing USB-It's based on the smartphone series. Here's the key difference:
| Smartphone series | Features of USB | Recommended method of extraction |
|---|---|---|
| Redmi Note 10/11 | USB-C 2.0 port, current restriction | Standard notice |
| Xiaomi 12/13 | USB 3.2 port, high speed recording | Through Settings or ADB |
| POCO F4/F5 | ExFAT support without additional drivers | File manager |
| Redmi 9/9A | Problems with OTG on some firmware | Reboot. |
For example, on Xiaomi 13 Ultra, when connecting an external SSD via USB-C, the system can “forget” to unmount it after removal, in which case only a full reboot helps.
And on the POCO X3 Pro with MIUI 12.5, a safe retrieval notification only appears after the drive has been idle without operations for more than 30 seconds.
Why some Xiaomis don’t have a “Remove” button
What to do if the storage device does not shut down
Situations when USB-The flash drive freezes and doesn't respond to extract commands, not uncommon:
- Check the active processes: 📱 Close all applications that may have accessed the drive (gallery, player, file manager). 🔍 Use Task Manager (Settings) → Annexes → Launched) for forced closure.
- Turn off data transmission: 📶 Transfer the smartphone to Flight Mode - it will interrupt background operations. 🔌 If the storage device is used for USB-modem, disable this function.
Forced unmounting:
- 🛠️ For root-access models, run in Terminal: su umount -l /mnt/media_rw/[ID_storage]
- 🔄 If nothing helps, restart your smartphone.
If the drive is still not turned off, and the data on it is critical:
- 🚫 Do not remove it by force – it can cause physical damage to contacts.
- 💾 Connect to your computer and check for errors using chkdsk (for Windows) or fsck (for Windows) Linux/Mac).
💡
On Xiaomi models with MIUI 14 and later, forced removal of the drive can lead to a locking of the USB-C port for 5 minutes (short-circuit protection).
How to avoid problems in the future
In order not to face freeze drives and data loss, follow these recommendations:
- 🔋 Use it. OTG-Powered adapters for external hard drives (they require more power than a smartphone port can give).
- 📁 Format flash drives in exFAT – this format is optimized for frequent connection / disablement.
- ⏱️ Always wait 10-15 seconds after you finish copying before retrieving (even if the notification has disappeared).
- 🔄 Update regularly MIUI — In new versions, bugs with USB.
For Xiaomi owners with USB 3.0/3.2 (e.g. 12S Ultra or Mix Fold):
- 🚀 Avoid connecting drives with a capacity of more than 1 TB - they may not be installed correctly.
- 🔌 Use original cables – cheap analogues do not support high transmission speeds.
💡
Create a folder on your smartphone USB_Temp And you can copy the files in front of the penos to the flash drive, which will reduce the risk of data loss in the event of a crash.
