Xiaomi Redmi Note 5 remains a popular device that supports connecting external drives via USB-OTG. Often users are faced with the need to clean the USB flash drive or change its file system to properly work with multimedia files. Standard Android tools allow you to perform this procedure quickly and safely without using a computer.
The formatting process removes all data from the media completely, so pre-preparation is crucial. Redmi Note 5 owners can use an integrated file manager or third-party utilities to complete the task. Below we will discuss in detail the algorithm of actions, possible errors and choosing the optimal file system for your use case.
Understanding the differences between file systems will help avoid future compatibility issues. Some formats may not be read by a TV or car radio if you choose the wrong one. The right setup ensures a stable speed of writing and reading data on your device.
Preparation USB-storage device and compatibility check
Before you start any manipulation of data, you need to make sure that the physical health of the equipment. Xiaomi Redmi Note 5 is equipped with a Micro-USB port, which requires a special OTG adapter or flash drive with the appropriate connector. Without the right hardware connection, software methods will not work, and the system simply will not see the external media.
⚠️ Warning: Make sure your smartphone battery is over 30% as the formatting process and the battery is used. USB-The port consumes additional energy.
Android's MIUI-based system automatically detects external storage connections. If a flash drive doesn't show up in the notification curtain after you connect, try restarting the device or checking the adapter's performance on another gadget. Sometimes the problem is that the charging port is dirty, which should be cleaned carefully.
It's important to understand that formatting is an irreversible process of destroying information. If you have important documents or photos on your flash drive, make sure you copy them to your computer or to the cloud in advance. Even if you plan to just clean the disk, backing up is the golden rule of digital hygiene.
💡
Use original or certified OTG adapter cables, as cheap analogues may not transmit data, but only provide charging devices.
Use of the built-in file manager
The easiest and most reliable way to format a drive is to use Xiaomi’s standard Explorer app, which is already pre-installed and optimized for the MIUI shell, eliminating the need for additional software.
To start the procedure, connect the flash drive to your smartphone and wait for the notification to appear. Open the Explorer app and go to the section «USB-In the top corner of the screen or in the settings menu (three dots), find the option “Settings” or “Information” where the button “Clean” or “Format” will be available».
The system will give you a warning that all the data will be destroyed. Confirm the action, and in a few seconds the drive will be ready to work. This method is ideal for quickly cleaning and creating a standard folder structure that the Android operating system understands.
☑️ Algorithm of actions in the conductor
File system selection: FAT32, exFAT or NTFS
One of the most important steps is choosing the format in which the drive will work. The file system determines how data is stored and organized on the disk. The Redmi Note 5 has three options, each with its own limitations and advantages depending on the purpose of use.
FAT32 is the most compatible format, readable by almost any device, from old radios to game consoles. However, it has a major drawback: the inability to write files larger than 4 GB. If you plan to store movies in high resolution, this option may not be suitable.
exFAT and NTFS are free of file size restrictions, but may require additional applications to be installed on some reading devices. Xiaomi Redmi Note 5 usually supports exFAT out of the box, making this format the optimal choice for modern tasks.
| Format | Max. File size. | Compatibility | Recommendation |
|---|---|---|---|
| FAT32 | 4GB | Maximum | For music and documents |
| exFAT | No restrictions. | Tall. | For movies and games |
| NTFS | No restrictions. | Medium (Windows) | To work with the PC |
| ext4 | No restrictions. | Only Android/Linux | To expand memory |
When choosing a format, consider where you will use the flash drive. Unless you use a smartphone and a modern TV, feel free to choose exFAT. For car stereo systems, you should leave the classic FAT32.
Formatting through Android settings
An alternative method of cleaning the drive is available through the system menu settings Android. This method gives deeper access to storage options and allows you not only to clean, but also to configure the flash drive as internal memory (although on new versions of Android this feature is often hidden).
Go to Settings. → In the list of available storage facilities, select yours. USB-You click on it, and you'll see a control menu where you have the "Format" option, and the system can tell you to choose how to work, whether it's portable storage or as part of internal memory.
⚠️ Note: When selecting the internal memory mode, the flash drive will be encrypted and cannot be read on other devices without re-formatting.
System settings are preferable if the standard conductor does not see the drive or is not working properly, and this method also allows you to check the overall health of the disk and the amount of space occupied before cleaning.
Why is the flash drive warming up?
Application of third-party applications for formatting
In some cases, standard MIUI tools are not enough, especially if you need formatting into specific file systems or repairing damaged sectors, and specialized applications from the Google Play Market come to the rescue.
One of the most popular tools is DriveDroid or USB OTG Helper. These programs provide enhanced control over the USB-They are port-based and allow low-level formatting, but they often require superuser rights to function properly).
If root is not available, you can use File Commander or similar file managers with advanced functionality, which allow you to format, but also test the write speed, which is useful for diagnosing old or suspicious flash drives.
Third-party software is justified when the built-in tools are in error or do not support the desired storage capacity, for example, some older versions of Android do not work correctly with flash drives larger than 128 GB without special drivers.
💡
Third-party applications are only needed in complex cases; Xiaomi’s built-in Explorer is enough for 95% of tasks.
Possible errors and methods of their elimination
During the formatting process, Redmi Note 5 users may encounter various system errors, most often the message “failed to format” or «USB-These errors do not always mean that the flash drive is physically broken.
One common cause is power shortages: The Micro-USB port may not provide enough current to run energy-intensive drives, especially if the smartphone battery is drained, in which case try to turn off all background apps or use a self-powered flash drive.
Another common problem is that the drive file system is corrupted logically, in which case formatting through a computer using the chkdsk utility or standard Windows drive management tools is performed, and after fixing errors on a PC, the smartphone usually recognizes the flash drive without any problems.
⚠️ Note: If the flash drive is not detected on any device and does not emit connection sounds, the memory controller is likely to have failed.
It is also worth checking the energy saving settings. MIUI Aggressive battery optimization can shut down power USB-Make sure that the battery settings do not limit the operation of the background processes of the system services.
