Owners of budget and mid-budget smartphones often face a lack of built-in storage, and the Xiaomi Redmi 8 is no exception.Despite the availability of a memory card slot, many users prefer to connect faster and more voluminous. USB-drives via a Micro-USB port with technology support OTG. However, before you can fully use an external drive or flash drive, the device will require a formatting procedure.
The process of preparing the drive on Redmi 8 has its own technical nuances related to the version of the MIUI shell and the limitations of the file system. Wrong actions can lead to loss of data or inability to read the device. In this article, we will discuss in detail how to format the flash drive correctly, which file system to choose for maximum compatibility, and what to do if the phone does not see the connected drive.
Preparation for formatting and compatibility check
Before you start any operations with the file system, you need to make sure that your hardware is physically ready to work. Xiaomi Redmi 8 has a Micro-USB 2.0 port that supports OTG (On-The-Go) function, but not all cables and adapters are of equal quality. Cheap adapters may not transmit enough voltage to run energy-intensive external hard drives, although conventional flash drives they tend to read without problems.
It's important to understand that formatting is a process that completely destroys all the data on the media. If there are important documents, photos or videos on the flash drive, be sure to copy them to your computer or to the cloud before you start the procedure. It's almost impossible to recover information after the low-level formatting that a smartphone does without expensive professional equipment.
Also, consider power consumption. If you plan to plug in bulk drives, make sure your Redmi 8 battery is at least 40-50%.A sudden power outage at the time of writing the partition table can damage the USB stick controller or the smartphone itself.
⚠️ Note: Use of unoriginal or damaged OTG-cables can lead to short circuit and failure of the power controller of the smartphone motherboard.
💡
Check the work. OTG-cable on another device before connecting to Redmi 8 to prevent adapter failure.
Make sure there is no physical protection against writing on the flash drive if it is a full-size card reader. SD-maps, though for USB-The presence of viruses on the media can also prevent the correct identification of the device by the system, so pre-checking with antivirus on the PC will not be superfluous.
Connection USB-drive-by
The process of connecting an external drive to the Xiaomi Redmi 8 usually goes automatically thanks to the Plug-and-Play feature built into Android. You do not need to install additional drivers or obtain root rights for basic work with files. OTG to the charging port, and then connect to it the flash drive.
After the physical connection at the top of the screen, in the notification area, the corresponding icon should appear. USB-The system can suggest you choose to use the mode: "File transfer" or "Facing only." To work with the data, you need to choose the first option. If the notification does not appear immediately, pull the "curtain" down and find a message about connecting the new device.
☑️ Connection check
In some cases, especially when using large-volume or high-power drives, the smartphone may issue a warning that the device consumes too much power. USB-Hub with its own power, so as not to overload the battery Redmi 8.
If you use a MIUI file manager, it will automatically open a window asking you to format the disk if the file system is not recognized, but we will look at the manual method through settings that gives you more control over the process.
Step-by-step: formatting through settings
The most reliable way to prepare a flash drive for working with Xiaomi Redmi 8 is to use the built-in system tools. This ensures that the partition structure is created correctly taking into account the features of the MIUI shell. First, go to the main menu of smartphone settings.
In the list of options, find a section that might be called About Phone, but we need Storage or Memory. Depending on the firmware version, the path may be slightly different: Settings → Phone → Storage or Settings → Storage. This displays information about internal memory and connected external media.
Find yours on the list. USB-It can be displayed as a storage device «USB-drive" or by manufacturer's name. Click on the device name to open the control menu. In the window that appears, select "Format" or "Clear" USB-accumulator».

Formatting through system settings is the most secure method that eliminates file system compatibility errors.
File system selection: FAT32, exFAT or NTFS
One of the most important issues when formatting is choosing a file system. Xiaomi Redmi 8, like most modern Android devices, supports several formats, each with its own advantages and limitations.
The most versatile option is FAT32, which is readable on almost any device, from old computers to game consoles to car radios, but it has a serious drawback: it doesn’t support storing files larger than 4GB. If you plan to record high-resolution movies on a flash drive, this format won’t work for you.
A more modern standard is exFAT. It has no file size limit and works well with large amounts of data. Redmi 8 works with exFAT without problems, but it is worth considering that on very old computers (for example, with Windows XP without updates), such a flash drive may not be determined.
NTFS is native to Windows and supports journaling, which improves data security in case of power failures. However, Android often supports NTFS only in read mode, or requires the installation of special applications for writing.
| File system | Max. File size. | Compatibility | Recommendation |
|---|---|---|---|
| FAT32 | 4GB | Maximum | For documents and music |
| exFAT | No restrictions. | High (Android, Win 7+) | For films and large archives |
| NTFS | No restrictions. | Medium (reading on Android only) | To work with the PC |
Why doesn’t the phone offer to choose a file system?
Use of Third-Party File Managers
If standard system tools fail to format the flash drive, or require finer configuration, you can use third-party software. Google Play store there are many applications that provide advanced access to the disk subsystem.
One of the most popular and functional tools is Total Commander, which is paired with the USB Stick Plugin. This app not only formats the drives, but also provides detailed viewing of folder structure, hidden files and attributes. The program interface may seem difficult for beginners, but it provides power comparable to desktop versions.
Another great option is DriveDroid (requires root) or simpler utilities like USB OTG Helper, which allow you to force the formatting process even if the system is “hanging” waiting for a response from the drive.
Some file managers allow you to create a bootable flash drive or split the drive into several partitions, which can be useful for advanced users using Redmi 8 for technical tasks.
Resolving errors and problems
Even if you follow all the instructions, users can encounter difficulties «USB-It's often a sign that the drive is corrupted" or "Not supported." Often it indicates that the flash drive is formatted in a file system that the phone can't read without additional encoding, or that there are logical errors in the partition table.
If Redmi 8 doesn't see the flash drive at all, try rebooting a smartphone with the drive already connected. USB-The controller doesn't have time to initialize when you're hot, and it's also worth checking if the debugging mode is on. USB» in the developer menu – in rare cases, it may conflict with the host mode.
⚠️ Warning: If the flash drive gets too hot during operation, turn it off immediately. Overheating may indicate a faulty controller or short circuit.
If the flash drive is detected but formatting is constantly interrupted or gives an error, it may have a physical malfunction or a broken sector, and you can check its condition using the chkdsk utility on your computer or specialized programs like H2testw.
Sometimes cleaning contacts helps. Wipe the Micro-USB connector on your phone and the contacts on the flash drive with dry soft cloth. Contact oxidation is a common cause of unstable connections and data transmission errors.
