Modern smartphones Xiaomi have ample memory expansion capabilities thanks to the support of technology OTG. Connecting an external flash drive or hard drive instantly increases the available space for photos, videos and documents. However, many users are faced with the question of the correct actions when shutting down work with external media.
Incorrectly shutting down the device can lead to serious consequences, such as damage to the file system or complete loss of saved data. The operating system Android and shell MIUI have built-in protection mechanisms that must be activated before physically removing the cable.
In this article we will analyze in detail software methods for disabling a USB drive on brand devices. Xiaomi. You will learn where the hidden settings are, how to interpret system notifications and what actions should absolutely not be performed during the transfer of information.
Why do you need to software disable a flash drive
Many smartphone owners mistakenly believe that it is enough to simply unplug the cable from the Type-C or Micro-USB connector. In fact, data recording or caching processes often continue to run in the background. If this process is physically interrupted, the memory controller may not have time to complete the operation.
The system Android uses buffering to speed up work with files. This means that information can be temporarily stored in RAM before being written to the drive itself. A soft eject sends a signal to the system to complete all open transactions and free up resources.
⚠️ Attention: Ignoring the secure eject procedure often results in a "File system is corrupt" error the next time you connect. Data recovery in such cases requires the use of specialized software on a PC.
In addition, some applications may keep files open even after you have closed the file manager. For example, the video player can continue buffering, and the antivirus can scan new documents. Only the “Eject” command guarantees a complete stop of all access to the disk.
Standard method through the notification panel
The fastest and most accessible way to disconnect an external drive on Xiaomi is using the notification curtain. This method works on most firmware versions MIUI and does not require a deep dive into the settings menu.
As soon as you connect the flash drive, the corresponding icon appears at the top of the screen. If the notification is hidden, just swipe down from the top edge of the display. In the list of active events, you will see a message about connecting a USB device.
- 🔍 Look for a notification that says “USB drive connected” or “Tap to set up USB.”
- ⚙️ Click on the gear icon or expand the notification to see additional options.
- 🛑 Select "Eject" or “Safely Remove”, which is usually displayed in red.
- ✅ Wait for the system message “USB drive can be removed.”
After the confirmation message appears, physically disconnecting the cable becomes completely safe. The system will automatically remount the file system and stop supplying power to the port in data transfer mode.
If the notification disappears too quickly, reconnect the flash drive and do not close the curtain until you complete all the steps.
Disable via storage settings
In cases where the notification panel does not display the necessary information or the interface was accidentally closed, you need to use the main settings menu. This path is more reliable, as it provides full control over connected devices.
The user needs to go to the Settingssection, then find the item Memory or Storage. Depending on the version MIUI, the name of the section may differ slightly, but the location logic remains the same for all smartphones Xiaomi.
Inside the storage menu, a list of all available partitions will be displayed memory. The external drive will be highlighted on a separate line, often indicating its capacity and name. Next to the name of the flash drive there is usually a control button or a menu with three dots.
Settings → About phone → Storage → USB drive → EjectBy clicking on the eject button, you initiate software dismantling of the volume. The screen may blink or a pop-up window may appear to confirm the action. Do not be alarmed if the flash drive icon in the status bar disappears instantly - this is a normal reaction of the system.

Features of working with file managers
Built-in explorer MIUI and third-party applications, such as Total Commander or FX File Explorer, can also manage the connection of drives. However, it is important to understand the difference between closing an application and disconnecting the device.
Simply minimizing or closing the file manager does not stop the operation of USB drivers at the system kernel level. The flash drive remains active, and the system still considers it connected, even if no application is explicitly using the files.
⚠️ Attention: Some file managers have their own “Disconnect” button in the interface. Use it only if you are sure that it sends a system signal and does not simply block access to folders within the application.
For maximum security, it is recommended to always duplicate actions through the system settings, even if you worked with files through third-party software. This ensures that all background processes running by the system will be completed correctly.
Why does the file manager not see the flash drive?
Sometimes Explorer does not display the drive due to a format conflict. If the flash drive is formatted in NTFS, the standard Xiaomi Explorer may require the installation of additional plugins or may not support writing, only reading.
Problems with the file system format
Format compatibility plays a key role in the stability of external drives on Android. The most common and recommended format is FAT32, which is supported by all devices without exception.
More modern formats, such as exFAT or NTFS, may require special support from the system kernel. On older smartphone models Xiaomi working with NTFS is often limited to read-only mode, which can cause errors when attempting to eject if the system considers the disk busy.
| Format | Compatibility | Max. file size | Recommendation |
|---|---|---|---|
| FAT32 | Full | 4 GB | Ideal for documents and photos |
| exFAT | High (Android 6+) | Without restrictions | Best choice for 4K video |
| NTFS | Partial (depending on the model) | No restrictions | Only for advanced users |
| EXT4 | Requires root access | No restrictions | Not recommended for transfer |
If you are using the format NTFS and encounter difficulties during extraction, try reformatting the drive to exFAT. This will solve most compatibility problems and ensure stable operation of USB drivers on your smartphone.
Diagnosing errors during ejection
Sometimes the system displays the message “Unable to eject the USB drive” or the button remains inactive. This indicates that some process is holding the file or directory on external memory. In such a situation, it is necessary to identify the culprit of the blocking.
Most often blocking is caused by media scanners, antiviruses or open documents in office applications. Close all running apps, especially those that have access to the storage, and try extracting again through the settings.
In rare cases, restarting the smartphone helps. If software extraction does not work and the data is not critical, you can turn off the phone completely. This is guaranteed to de-energize the USB port and stop all processes, but is a last resort.
⚠️ Attention: Never unplug the cable if the flash drive activity indicator (if there is one) is blinking, or if you have just copied a large file. The risk of data loss at this moment is maximum.
It is also worth checking whether the flash drive is being used as internal storage (Adoptable Storage). In this mode, the system integrates it into the overall memory structure, and simple extraction is impossible without first transferring the data back to the internal disk.
If the eject error message appears constantly, check the list of running applications and force stop those that work with files.
Frequently asked questions (FAQ)
Is it possible to turn off the phone instead of safely removing it?
Yes, completely turning off the smartphone is the most a reliable way to turn off any external devices. When the system is de-energized, all recording processes stop instantly, which eliminates data damage. However, this takes longer than software extraction.
Why does the flash drive heat up when connected to Xiaomi?
Slight heating of the drive case is a normal physical phenomenon during active data transfer and controller operation. However, if the flash drive becomes scorching hot, the USB port may be putting out too much voltage or there is a problem with the drive itself.
What to do if the phone does not see the flash drive after removing it?
Try connecting the drive to another device to check its functionality. If the problem is with your smartphone, clean the USB port from dust and restart the device. Sometimes it is necessary to reformat the flash drive into a compatible format.
Does the case affect the connection of the USB cable?
Yes, some thick protective cases may prevent the cable plug from fully inserting into the Type-C connector. This leads to unstable contact and frequent shutdowns. In such cases, it is recommended to remove the cover when working with external drives.
