USB-Drives remain one of the most versatile ways to carry data, despite the development of cloud services. -- Xiaomi smartphone owners (including the Redmi series, POCO, Mis often face the need to clean the flash drive directly from the phone — whether it’s deleting unnecessary files, preparing to write new information or solving reading problems. However, standard methods of formatting via PC are not always convenient, especially if only a smartphone is on hand.

In this article, we will discuss all the current cleaning methods. USB-Drive directly on Xiaomi devices, including hidden features MIUI, Third-party applications and avoidance of common errors (e.g., "Disk is Write-Protected" or "File System Not Supported").

USB-Drive damaged or It is impossible to format the disk, here you will find working solutions.

Why? USB-The storage device is not cleaned by standard methods?

Problems with formatting flash drives on Xiaomi are most often due to file system limitations or hardware locks.

• 🔒 Write protection: Physical switch on the flash drive body (relevant for older models) or software lock.
• 🗑️ Damaged sectors: The drive may have broken clusters that interfere with complete cleaning.
• 🖥️ Incompatible file system: Xiaomi based MIUI default supports FAT32 and exFAT, but not NTFS (rootless).
• 📱 Android Restrictions: The system may block formatting due to access rights or security policies.

For example, if you try to format a 64GB or more flash drive into FAT32 through a standard file manager, the operation can end in error, due to the FAT32 limitation on file size (maximum 4GB) and partition space (up to 32GB in some implementations), the solution is to use exFAT or specialized utilities.

Method 1: Formatting through the MIUI file manager

The easiest method is to use the standard File Application (or File Manager in global firmware), which is suitable for flash drives up to 32 GB and the FAT32 file system.

2. Open the Files app and go to the section USB-drive (usually displayed as a removable disk).

• 🔌 The drive is connected in Read Only mode (check the adapter or cable).
• 📁 The flash drive is used as portable storage for applications (disable this feature in Settings). → Memory).
• 🛠️ The device has physical damage (try connecting to the PC).

💡

2. Connect the flash drive and open the app. The drive will show up in the list of devices.
3. Choose. USB-disk → press Format.
4. Specify the file system: FAT32 - for compatibility with all devices (max. file size 4 GB). exFAT - for flash drives over 32 GB (max. file size 16 EB). NTFS - only for experienced users (requires root or PC).
