Modern smartphones Xiaomi, Redmi and POCO They have enormous potential to work with external drives, and owners often wonder how to open a shiaomi flash drive to view high-resolution movies or move gigabytes of photos. USB-The storage device via the charging connector is a standard function known as OTG (On-The-Go, which is built into the shell MIUI and HyperOS by default.
However, despite the simplicity of the process, users sometimes face difficulties: the device does not see the drive, requires formatting or gives out a file system error. In this article, we will discuss in detail all aspects of the connection, from choosing the right adapter to configuring hidden developer parameters that can block access to data.
Before you get to the complex settings, you need to make sure that your equipment is physically compatible. Not every adapter is able to provide stable data transfer, especially if you are talking about capacious USB 3.0 drives. Let's look at the basic requirements and steps for a successful start.
Requirements for OTG equipment and adapters
The first step to successfully connect is to have a quality adapter. Xiaomi smartphones use USB Type-C or Micro-USB connectors (in older models), and a standard USB-A flash drive requires an adapter. It is important to understand that cheap cables without shielding may not transmit data, working only for charging.
And it also matters how much power you're using to connect your device, and if you're trying to connect an external hard drive, you might not have enough power to promote it. USB-A powered hub, and for normal flash drives, a passive adapter that supports the standard is enough. USB 3.0 for maximum speed.
Make sure your smartphone supports OTG technology. Virtually all Xiaomi models released after 2016 have this feature out of the box. You can check for support in the specifications on the official website or in the Mi Specs app.
When choosing an accessory, pay attention to bandwidth. 4K-A cheap transmitter can't pull the stream, causing delays and jerks. A high-quality cable is the foundation of stable file management.
The process of physically connecting the drive
The connection procedure is as simple as possible and does not require root rights or complex configurations. You do not need to search for special switches in the menu before inserting a flash drive. Android system in conjunction with the MIUI shell automatically responds to the appearance of a new device.
Insert the adapter into the charger connector of your smartphone. If there is an LED indicator on the flash drive, it should light up or blink, signaling the power supply. 1-2 a second at the top of the screen, in the notification area, should appear icon USB-storage.
☑️ Connection check
⚠️ Warning: Never pull the flash drive abruptly while writing or reading files.This can damage the file system and cause data loss. Always use the Safe Retrieval feature.
After the notification appears, the system will prompt you to open the file manager or start the media player. If nothing happens, pull the notification curtain down and find the message about the connected device. USB-Pressing it will open up the contents of the drive.
Access through the file manager
The standard tool for working with files in Xiaomi smartphones is the Explorer app (or File Manager), which navigates through internal memory and connected external drives. After connecting the flash drive in the main menu of the conductor, a new section will appear.
It is usually denoted as USB or the name of the drive manufacturer (e.g. SANDISK, KINGSTON). Going to this section, you will have full access to folders and files. The interface allows you to sort data by date, size or type, and copy files between internal memory and the flash drive.
If the automatic start-up didn’t work, open the Explorer app manually. At the top of the screen, there are often tabs or drop-down menus where you can switch between internal storage and external storage (USB Storage).
Why is the flash drive not displayed in the Explorer?
For easy work with documents and photos, it is recommended to use the Favorites feature, you can add frequently used folders from a flash drive to your favorites to quickly access them without deep navigation, which is especially useful with regular data exchange.
Solving NTFS and FAT32 Formatting Problems
One of the most common problems is file system incompatibility. Android natively supports formats. FAT32 However, many flash drives and external drives are formatted in NTFS (Windows standard. Standard conductor MIUI may not see such drives or offer formatting.
Formatting will destroy all data on the media. If there is important information on the flash drive, don't agree to formatting right away. There are alternative solutions. You can use third-party file managers, such as MX Player (for video) or Total Commander with a USB plugin, which can read NTFS without rewiring the disk.
If the data on the flash drive is not important or you have already made a copy of it, the easiest way to format the drive into a compatible format right on your smartphone, the system will suggest doing this when you try to open an incompatible device.
| File system | Xiaomi support | Max. File size. | Recommendation |
|---|---|---|---|
| FAT32 | Complete. | 4GB | For flash drives up to 32GB |
| exFAT | Complete. | No restrictions. | Optimal for large volumes |
| NTFS | Partial (Plugin needed) | No restrictions. | Only for Windows PC |
| ext4 | Only Root. | No restrictions. | For advanced users |
The choice of exFAT format is the most sensible solution for modern users: it is compatible with Windows, macOS and Android, and also has no limit of 4 GB per file, which is critical for storing high-quality movies.
Using third-party applications to read USB
When built-in tools fail to open the flash drive, specialized applications come to the rescue, they have their own drivers and can bypass the system limitations of the MIUI shell, which is especially true for older models or specific file systems.
One of the best solutions is the USB OTG Helper or File Commander app, which scans the connected device and provides an interface to copy, move, and delete files. They can often read a drive that the system considers corrupt.
💡
Use the VLC for Android app to play back flash drive videos. It has built-in support for USB and codecs, which solves 90% of movie playback problems.
Such applications may require permission to access USB-When you first start up, the system will issue a request that you need to confirm. Without that permission, the program will not be able to "see" the connected drive.
⚠️ Warning: Be careful when installing applications from unknown sources. download file managers only from the official Google Play store or GetApps to avoid viruses.
Some video players, such as the MX Player, require a separate activation of the USB function. To do this, you need to go to the player settings, select the Network and Storage section and enable the USB option.
Diagnostic errors and why the phone can’t see the flash drive
If after all the manipulations, the Xiaomi smartphone did not see the flash drive, you need to conduct a diagnosis. The problems can be hardware (a port failure, a burned-out USB controller) or software (driver conflict, system failure).
Try connecting the flash drive to another device (computer or other phone) if it doesn't work anywhere, it's likely the drive is faulty. If everything opens on a PC, the problem is with the smartphone settings or adapter.
A common cause is contamination of the USB Type-C port. The pockets are stuffed with dust and pile, which prevents close contact.
💡
If the phone does not see the flash drive, in 80% of cases the problem is solved by replacing the OTG adapter or formatting the drive in exFAT.
Also worth checking is the energy saving settings. In rare cases, aggressive energy saving can shut off power to the USB port when battery power is low. Make sure your smartphone is above 20%.
Safe removal and disabling of the device
Properly disabling the flash drive is key to the integrity of your data. Simply pulling the device out can cause the file system to be labeled as corrupt and the next time you connect, the smartphone will require formatting.
For safe extraction, lower the notification curtain. Find the connected notification USB-Next to the device name or notification menu should be a button “Disable” or an extract icon (triangle with a line).
When you press the button, the system will complete all the recording operations and turn off the port power, and you will notice that the drive can be safely removed, and then you will physically remove the flash drive.
If you use a third-party file manager, the secure extraction function may be inside the application itself. Look for a button with an up arrow or an Eject in the program interface.
