Modern smartphones like the Xiaomi Redmi Note 8 have a large amount of internal memory, but when you are actively working with media or downloading heavy files, the place still tends to end. In such situations, external drives that are connected through the USB Type-C port come to the rescue.
The cause of these failures is often incompatible file system or logical errors in the structure of the drive. Formatting is the process of creating a new file markup that allows you to bring the flash drive to a state that is understandable to the Android operating system. If you are faced with the inability to copy a photo or run video from an external drive, this procedure is the first and most effective step in solving the problem.
It is important to understand that formatting will completely destroy all data on the media. Before you start taking action, you need to make sure that important documents and photos are stored on your computer or in the cloud. In this article, we will discuss in detail how to properly prepare and format a flash drive on a Redmi Note 8 model using built-in system tools or third-party software.
Preparation for the procedure and check the compatibility of the OTG
Before you start formatting, make sure your Xiaomi Redmi Note 8 is technically ready to work with external drives. This model supports USB OTG (On-The-Go) technology, which allows the smartphone to act as a host and supply power to the connected device. However, not all flash drives are equally friendly to mobile operating systems, and some of them may require too much power.
If you use a regular USB drive, you will need a special adapter or USB Type-C to USB-A cable. In the case of modern flash drives that have two connectors at once, you do not need an adapter. Make sure that the contacts are clean and not oxidized, as poor contact can lead to interruption of the formatting process, which can damage the memory controller.
⚠️ Note: If your flash drive has an LED light, it should not flash or go out quickly immediately after you connect. This may indicate a power shortage. In this case, try using a shorter cable or turn off energy-intensive applications in the background.
It’s also worth checking if USB debugging is activated, although it’s rare for basic formatting. The main requirement is a stable connection. If the phone makes the device’s connection sound but doesn’t display it on the menu, the problem may lie in the drivers or a physical malfunction of the smartphone’s Type-C port itself.
File system selection: FAT32, exFAT or NTFS
One of the keys before starting the procedure is choosing the right file system. Android, based on the Linux kernel, has its own preferences and limitations. The most universal standard for mobile devices is FAT32. It provides maximum compatibility, allowing you to read data not only on your phone, but also on tape recorders, TVs and old computers.
However, FAT32 has a significant drawback: it does not support burning files larger than 4 GB. If you plan to store high-resolution movies or game images on a flash drive, you will need a more modern system - exFAT. It is free of file size restrictions and works great with large amounts of memory, but may not be readable on some older devices without installing additional drivers.
NTFS, a native file system for Windows, runs on Android, but without special applications or root rights, a smartphone can often only read data from such a drive, but not write new ones, so it is better to choose FAT32 or exFAT for using the flash drive as an expandable memory of the phone.
| File system | Max. File size. | Compatibility with Android | Recommendation |
|---|---|---|---|
| FAT32 | 4GB | Complete (native) | For documents, photos, music |
| exFAT | No restrictions. | Complete (native) | For 4K video, large archives |
| NTFS | No restrictions. | Reading only (no root) | For porting from PC without formatting |
💡
If you don’t know which system to choose, stop at exFAT.It combines the reliability of NTFS and compatibility with modern versions of Android installed on the Redmi Note 8.
Formatting through built-in Android settings
The easiest and safest way to get the drive in order is to use the standard functionality of the MIUI shell. This method does not require the installation of additional software and minimizes the risk of user error. First, connect the flash drive to your smartphone and wait for the corresponding notification to appear in the top panel or icon in the menu.
Next, follow the settings menu. Find the Settings section, then select About Phone or go straight to Settings -> Advanced settings -> Memory. In some versions of the firmware, the path may look like Settings -> Storage. On the list of available drives, you should see your flash drive, often labeled as USB-storage device.
Click on your flash drive name to open the control menu. There will be a Clean button available. USB-It will alert you that all data will be deleted, and once confirmed, a process will begin, which usually takes between a few seconds and a couple of minutes, depending on the amount of memory.
☑️ Algorithm of formatting in MIUI
Once the operation is complete, the system will automatically mount the file system and the drive will be ready to go. If there is an error in the process, try to remove the device and connect it again, or restart the smartphone before trying again.
Using the MIUI application for cleaning
Owners of the Xiaomi Redmi Note 8 often overlook the built-in Security app, which also manages external drives.This tool is sometimes more informative than the standard settings menu and can offer additional verification options. Launch the Security app and find the Cleanup or icon section at the bottom of the screen USB-The storage device, if it is already connected.
The status of the connected device can be displayed inside the application, and if the system detects file system errors, it will prompt it to fix them or format the drive, and this is a convenient way of diagnosing: if the built-in analyzer sees problems with the structure of sectors, standard formatting may not help, and deeper intervention will be required.
It's worth noting that MIUI Security can run in the background and scan files for viruses immediately after you're connected, which can temporarily slow down your phone or formatting process, and wait until the initial scan is finished before you start the cleanup process.
⚠️ Warning: Do not remove the flash drive while the Security app is scanning or formatting, and this is guaranteed to cause logical damage to the partition table.
Why can't the Security app see the flash drive?
Formatting through third-party applications
If the standard Redmi Note 8 methods fail to do the job, such as giving you a “failed to format” error or not seeing the drive at all, specialized utilities will come to the rescue. One of the most popular and reliable is the DriveDroid application (requires root) or simpler analogues like USB OTG Helper and File Commander. They have their own drivers and algorithms for working with memory.
Consider the process using the example of a file manager with advanced functionality, for example, X-Plore or ES Explorer. Once you install the application and give it all the permissions you need, plug in the flash drive. In the program interface, select the connected one. USB-In the action menu (usually three dots or a menu button), find Format or Format Device.
The advantage of third-party software is that you can choose a specific file system, even if the Android system defaults to only one.You can force ext4 (if you plan to use a flash drive only with that phone and possibly root rights) or NTFS with recording support.
However, using third-party software carries risks: an incorrect application can write an incorrect partition table, after which the USB drive will have to be restored on the computer. Always check the ratings of applications in Google Play before installing.
💡
Third-party applications are "heavy artillery," and use them only if the built-in tools can't format the drive, because they give you more control, but they require care.
Solving and eliminating errors
Even if you follow all the instructions, users of Xiaomi Redmi Note 8 can face various errors — «USB-The drive is corrupted" or "File system is not supported. " Often this means that the flash drive was formatted on the computer in the system. NTFS without a recording right, or sector zero is damaged.
If the phone says that the drive is empty or has a size of 0 bytes, the USB flash drive controller may have burned down or it was improperly removed in the past, in such cases, connect the USB drive to the PC and perform low-level formatting with special utilities, such as the HDD Low Level Format Tool, then try connecting to the phone again.
Another problem is the reconnection cycle, and the phone sees the flash drive and loses it, which is a classic sign of power shortage or overheating. USB The Type-C port on the Redmi Note 8 may not provide enough current for high-power drives. USB-powerhouse.
- 🔌 Connection error: Check the cable OTG On integrity, try flipping the plug (although Type-C is symmetrical, the contacts can oxidize on one side).
- 💾 Recording error: Make sure that the flash drive does not have a physical recording protection switch (Lock) installed if you use a card reader.
- 🔋 Fast discharge: Working with an external flash drive significantly increases power consumption. Watch the battery level while transferring large files.
⚠️ Attention: If the flash drive continues to malfunction after formatting on different devices, there is a high probability of its physical failure.
In conclusion, maintaining external drives properly extends their life and keeps your data intact, check your flash drives regularly for errors, and back up important information without relying on one medium.
