Formatting a flash drive via Xiaomi Redmi 8 Pro is a challenge that users face when they need to clean the drive, change the file system or fix reading errors. Unlike a PC where the process takes a couple of clicks, Android devices have their own peculiarities: MIUI limitations, the choice between FAT32/exFAT/NTFS and the risk of data loss if you do not do it correctly. This guide will help you understand all the nuances from preparing the drive to solving typical problems.
It's important to understand that Redmi 8 Pro (codenamed olivewood) is based on MIUI, which imposes restrictions on external media, for example, the standard Files application does not always correctly handle flash drives larger than 64 GB, and some file systems (like NTFS) may not be supported out of the box. We'll look at all the available methods, from embedded tools to third-party applications, and explain why it's sometimes better to use a PC.
Preparation of the flash drive for formatting on Redmi 8 Pro
Before you start cleaning the drive, follow a few critical steps, and neglecting them can lead to data loss without the ability to restore or even damage the drive itself.
First, back up all important files, and even if you plan to format an empty flash drive, check it for hidden files (like Android system folders or app cache).
- 🔍 Connect the flash drive to the phone through OTG-adapter (if microSD is used) or insert into the slot.

Second, check the physical state of the flash drive, and if the drive is detected with errors (e.g., asks you to format it every time you connect), it may indicate:
- 💥 Damaged sectors (try scanning on PC with CrystalDiskInfo).
- 🔌 Contact problems (clean the connector with alcohol and check the adapter) OTG).
- 🦠 Viral infection (especially if the flash drive has been previously used on a PC).
⚠️ Warning: If the flash drive makes extraneous sounds (clicks, squeaks) or gets very hot, don't format it - these are signs of mechanical wear.
Method 1: Formatting through the standard application "Files"
The easiest method is to use the built-in MIUI file manager, which supports basic operations with external media, but has limitations:
- ✅ Works with FAT32 exFAT (NTFS read-only).

- Connect the flash drive to your phone (via OTG or memory card slot).
- Open the Files app (the folder icon on the desktop).
- Go to Device → find your drive (the name depends on the flash drive model).
- Click on the three dots in the upper right corner → Settings → Format.
- Select the file system (exFAT is recommended for flash drives >32 GB).
- Confirm the action, wait until the completion (usually takes 1-5 minutes).
⚠️ Warning: If the flash drive is not identified after formatting, try re-engineering it and reconnecting it. Sometimes the Redmi 8 Pro requires a reboot to properly mount the drive.

File System Choice: What’s Best for Redmi 8 Pro
The file system depends on the compatibility of the flash drive with devices, the maximum file size and speed. For Xiaomi Redmi 8 Pro, three options are relevant:
| File system | Max. File size. | Max. The volume of the flash drive. | Pluses | Cons |
|---|---|---|---|---|
| FAT32 | 4GB | 32GB | ✅ Compatibility with all devices✅ Low wear of the flash drive | ❌ File size limitation❌ Ineffective for large volumes |
| exFAT | 16 EB | 128 PB | ✅ There are no restrictions on file sizes✅ Optimized for flash drives | ❌ Not supported by older devices (until 2010) |
| NTFS | 16 EB | 16 EB | ✅ Support for access rights✅ Journaling (proof against failures) | ❌ Android only reads (no root)❌ High wear of the flash drive |
