Modern smartphones, including the popular Xiaomi Redmi 4X, Often faced with a lack of built-in memory for storing multimedia content. users are actively using external drives connected through the Internet. OTG-However, before the first use or if there are read errors, you need to format the drive before the first use or if you have read errors.
The process of preparing external data storage based on the Android operating system has its nuances. Incorrectly selected file system can lead to the fact that the phone simply will not see the connected device. In this article, we will discuss in detail how to safely and correctly format the flash drive on the Xiaomi Redmi 4X, avoiding loss of important data.
Before you start manipulating the file system, you need to make sure that the hardware is compatible. Your smartphone should support OTG technology, which is standard for the 4X model. It is important to understand that formatting will completely destroy all files on the media, so pre-backup information to the computer is a must.
The formatting procedure is run directly through the system settings of the MIUI interface. It is an integrated tool that is optimized to work with peripherals without the need to install third-party software.
⚠️ Before starting the procedure, make sure that your Redmi battery is charged. 4X is 30-40%. Sudden power outage during sector recording process can cause software damage to the flash drive controller.
If the automatic notification doesn’t appear, you’ll need to manually navigate to the memory management menu, which is standard practice for all firmware versions, whether it’s the old MIUI 9 or newer builds based on Android 6.0. The interface may differ slightly visually, but the logic of the actions remains unchanged.
⚠️ Attention: Don't pull out USB-Mechanical damage to contacts or software failure during formatting can make the device unreadable without special equipment.
Owners of Xiaomi Redmi 4X Note that the device is running on a Snapdragon 435 processor, which has limitations on the recoil current on the device. USB-If your flash drive requires a lot of energy (for example, volumetric). SSD-Disk without power, the phone may not start the formatting process due to lack of power.
Preparation of equipment and compatibility check
The first step is to physically connect an external media. For the Redmi 4X, you will need an OTG adapter (Micro-USB on USB Type-A). The quality of the cable plays a critical role: cheap Chinese adapters often don't have the necessary jumpers to transfer data, providing only charging.
After you connect, pay attention to the notification panel. The system should emit a characteristic sound and show the icon. USB-If there is no reaction, try another cable or check if the function is on. OTG In some versions, in some versions. MIUI You need to manually activate this item.
Check the file system on your computer if you can. Xiaomi Redmi 4X natively supports FAT32 and exFAT. NTFS file system, popular in Windows, may not be readable without installing additional drivers or applications like Microsoft exFAT/NTFS for USB by Paragon.
💡
Use the original or certified OTG-Cheap analogues often lead to data transmission errors and can damage the charging port of a smartphone due to voltage surges.
Visually inspect the connectors for oxidation or dust. Mud in the Micro-USB port is a common cause of unstable connections when the phone sees the flash drive and loses it. Cleaning the port with a soft brush can solve the problem before you start the software setup.
Formatting through the standard settings menu
The safest and most recommended way to prepare the drive is to use the system’s regular tools, which ensures that the partition structure is properly structured, understandable to MIUI. You don’t need root rights or complex utilities.
To start, go to the settings section. The path may vary, but most often it looks like Settings. → Memory or Settings → The phone. → Memory. The list of connected storages should show yours. USB-accumulator.
☑️ Pre-formatting verification
Click on your flash drive name. The device management menu will open. You're interested in the "Clean"/"Format" button or option. The system will again warn you of data loss. Confirm the action, and the process will take from a few seconds to a couple of minutes depending on the volume.
⚠️ Note: If there is no formatting button in the menu, it is possible that the flash drive is already formatted in a compatible system or, conversely, is physically damaged.
Once the operation is completed successfully, the system will issue a notification of readiness to work. Now you can copy files. Xiaomi Redmi 4X will automatically create the necessary folders for media files, if they have not been created before.
Use of the Application Conductor
An alternative method is to work through the built-in file manager, which is convenient if you are already in the file management menu. Open the Explorer (or File Manager) application on the desktop.
At the top of the screen or in the side menu, select the tab responsible for external drives (usually marked with a USB icon).Tap three dots in the corner of the screen or hold your finger on the flash drive name to call the context menu.
In the list that appears, select Format. This is identical to the first one, but sometimes it works faster because it passes the extra layers of system settings. For Redmi 4X, it is a standard procedure that requires no special skills.
Why is the flash drive not formatted through the Explorer?
Some users prefer third-party file managers, such as Total Commander or ES Explorer. They also have formatting, but use the same Android system calls.
Selection of File System: FAT32 or exFAT
When formatting, it's a matter of file system choice. This is a critical point for compatibility. Xiaomi Redmi 4X, like most Android devices, works best with FAT32.
FAT32 is highly compatible, and a flash drive formatted in this system can be read by a TV, a car radio, a game console, and any computer, but FAT32 has a limitation: it does not support recording files larger than 4 GB.
| Parameter | FAT32 | exFAT | NTFS |
|---|---|---|---|
| Max. File size. | 4GB | No restrictions. | No restrictions. |
| Compatibility with Android | Native. | Native (on new versions) | Requires drivers |
| Compatibility with TV/auto | Tall. | Medium | Low. |
| Stability of work | Tall. | Tall. | Medium |
The exFAT format is free of the 4GB limit and ideal for high-resolution movies or large archives. If your Redmi 4X is running on the current firmware version, it should recognize that format correctly. Older versions may require a patch.
💡
To use the flash drive in your car or on your TV, choose FAT32. To store movies over 4GB on your smartphone, exFAT.
NTFS is not recommended for Xiaomi phones unless absolutely necessary, and it's a journaled file system that puts extra strain on the phone's controller and puts the battery down quickly, and it also requires the installation of special applications to work.
Solving errors in formatting
Users often encounter a message that says “failed to format” or «USB-The first reason is that the drive itself is damaged, and you can check it on your computer with chkdsk or third-party software.
The second reason is the lack of power. - Xiaomi Redmi 4X It has a 4,100 mAh battery, but the port's current is limited. HDD The disk, the phone may not be able to pull it. Use the active drive. USB-feed-in.
The third problem is software failure, and sometimes the vold (Volume Daemon) process that runs the volumes freezes, so simply restarting the smartphone before trying to connect again will help.
What if the flash drive is defined as 0 bytes?
It’s also worth checking for system updates. Older MIUI builds may have bugs patched in security patches. Updating to the latest available version for your model can solve the compatibility issue.
Use of third-party applications
If regular funds fail, specialized applications from Google Play come to the rescue, the leader in this area is the DriveDroid app (requires root) or USB OTG Helper.
For users without root rights, File Commander or Solid Explorer are great. They have built-in modules for working with the Internet. USB. After installing the application, request access USB-device in the system window that appears.
In the program interface, find the connected drive and select the formatting function. Note that some applications may offer the creation of bootable images, which is not required for a regular flash drive with photos and music.
💡
When using third-party programs, always choose the option “Fast formatting.” Full formatting takes a long time and puts an unnecessary load on flash memory with no apparent benefit to the average user.
Remember, third-party software doesn't have more privileges than the system itself. If MIUI can't format a flash drive because of a hardware bug, then the Format Tool app can't do that. There's no miracle.
