Modern smartphones like the Xiaomi Redmi Note 8 Pro have an impressive amount of internal memory, but it is not unlimited. Often users are faced with the need to expand storage to watch movies in high resolution, listen to music or transfer large working files. In such situations, external drives connected through the port come to the rescue. USB Type-C.
However, before a device can work properly with your gadget, it often requires pre-production. The process of bringing the drive to the desired standard is called formatting. This action cleans the disk and creates a new file system that is understandable to the Android operating system and the MIUI shell.
Owners of the Redmi Note 8 Pro should be aware that not all flash drives work out of the box. Sometimes the system simply does not see the device, and in other cases asks for permission to write. Properly performing all the steps ensures the safety of your data and a stable speed of information transfer.
Equipment preparation and OTG compatibility check
The first step is to physically connect an external drive. Xiaomi Redmi Note 8 Pro supports USB On-The-Go technology, which allows the smartphone to act as a host. To connect, you will need the flash drive itself and possibly an adapter if it has a classic USB-A connector, not a Type-C.
Make sure your external drive is working. It's best to check it on your computer before you connect to your phone. If the flash drive has an LED light, it should catch fire or blink after connecting to the smartphone port. Lack of reaction may indicate a power shortage or port damage.
Shell MIUI It usually automatically recognizes the connected device. A pop-up notification of a new device should appear on the screen. USB-If that doesn't happen, try re-inserting the flash drive and making sure it's locked into the connector.
💡
Use the original Xiaomi adapter or quality certified cables, as cheap analogues can not transmit data, but only charge the device.
⚠️ Warning: If the smartphone starts to discharge or heat up quickly after you connect, immediately turn off the flash drive. This may indicate a short circuit inside the drive.
Use of built-in MIUI tools for formatting
Android provides built-in tools for working with disks. In Xiaomi smartphones, this feature is integrated into the storage settings menu. To access them, after connecting the flash drive, go to the main settings menu of the device.
Find the partition that's responsible for memory. Different versions of the firmware may call it different things, like Settings. → The phone. → Storage or simply Settings → Memory. In the list of available drives, you'll see internal memory and connected disks. USB-accumulator.
Click on your flash drive name. The management menu will open, where you can view content, extract and, most importantly, format. Select Format (or Erase) and the system will warn you that all data will be deleted.
☑️ Pre-formatting verification
Confirm the action. It takes from a few seconds to a couple of minutes, depending on the size of the drive, and when it's done, the system will give you a message that it's done successfully, and the flash drive will be ready to write files.
Application of third-party applications for advanced settings
The regular MIUI tools are good for basic tasks, but sometimes they don't allow you to choose a specific file system or cluster size. In such cases, specialized utilities from the Google Play Market come to the rescue. One of the most popular and functional is the DriveDroid application or USB OTG Helper.
Once you install the application, launch it and give you the necessary permissions to access the file system. The program will scan the connected devices and give you a list of available actions.
In the tool menu, find the formatting option. Here you may be asked to choose the file system type. For Xiaomi smartphones, the most compatible formats are FAT32 and exFAT. The choice depends on the size of the files you plan to write.
What is the difference between FAT32 and exFAT?
Using third-party software is especially important if the built-in menu is a bug or freezes. Apps often have more detailed error logs, which helps diagnose the problem.
Selection of File System: FAT32, NTFS or exFAT
Choosing the right file system is a critical step, and it depends on whether your Redmi Note 8 Pro can read files and open them on other devices, such as a TV or a computer.
FAT32 is the most versatile format, supported by almost any operating system and appliances, but it has a significant limitation: a single file can't exceed 4 gigabytes, and if you plan on watching 4K movies or storing disc images, it's not going to be the right format for you.
The exFAT format is designed specifically for flash drives, it removes the file size limit and works efficiently with large amounts of memory. Xiaomi Redmi Note 8 Pro works perfectly with this format. It is the optimal choice for modern users.
NTFS is native to Windows. Android-based smartphones can often read these flash drives, but writing them may not be available without special drivers or root rights. Use NTFS on your phone is recommended only in specific cases.
| File system | Max. File size. | Compatibility with Android | Best application |
|---|---|---|---|
| FAT32 | 4GB | Complete. | Documents, music, photos |
| exFAT | No restrictions. | Complete (Android 6.0+) | 4K movies, big archives |
| NTFS | No restrictions. | Reading/Recording (often needing help) | Working with Windows PC |
Solving Errors in Connection and Formatting
Despite the simplicity of the procedure, users may encounter difficulties"USB-"Device is corrupted" or a request to format a disk that ends in an error, which could mean logical failure or physical damage to sectors.
If the formatting is not complete, try using a computer.Plug the flash drive to your PC, complete the formatting in FAT32, and then try connecting it to Xiaomi again.Occasionally cleaning the partition table through the Windows command line (diskpart command) helps, but it takes care.
Another cause of error is a lack of food. USB In a smartphone, it has a limit on current. If you plug in a volumetric external hard drive (HDD), It may not have enough energy, and then it needs to be active. USB-powerhouse.
⚠️ Warning: Do not remove the flash drive while writing data. This is guaranteed to damage the file spreadsheet and lose information. Always use software extraction through the notification curtain.
Also worth checking is the power saving settings. In some modes, MIUI may limit the current to the USB port to save battery power. Switch USB mode to the developer menu or connection settings if this option is available.
💡
If the flash drive is not detected after formatting on a PC and phone, it is likely to be physically faulty and need replacement.
Automatic connection setting and data security
After successful formatting, it is important to set up the right drive. Android allows you to use the flash drive as a portable storage or, in rare cases, as part of internal memory. The Redmi Note 8 Pro recommends a portable drive mode.
In this mode, all photos and videos taken on the camera can be saved by default to an external drive. To do this, go to the camera settings and select the save location. SD-map USB-It'll free up precious interior space.
Keep in mind security. If you lose a phone with a flash drive connected, the finder will have access to all your files, use the built-in drive encryption feature if this option is available in your version of MIUI, or store data in secure folders.
Regularly check data integrity. Periodic formatting (once every six months to a year) helps prevent broken sectors and reading errors, prolonging the life of your drive.
