Removing the flash drive from a Xiaomi smartphone seems like a simple operation, but the wrong actions can lead to file damage, drive failures or even slot failure. This problem is especially relevant for owners of devices with hybrid slots (for example, Redmi Note 12 Pro).+ or POCO X5 Pro, where the microSD shares space with SIM-In this article, we'll look at not only the standard extraction method, but also the nuances for different models, and what to do if the phone doesn't see the flash drive after extraction.
It's important to understand that the process varies depending on the type of drive. For USB-OTG flash drives (connected via an adapter) and embedded microSD algorithms are different. We'll look at both options, and we'll also tell you how to check if the drive is currently in use by the system - this is the key point before extraction.

- 🔴 Data loss – if the file was opened in the application (for example, a video in a gallery or a document in the app) WPS Office, it could be damaged.
- 🔴 Failure of the file system – when writing data (for example, while shooting a video on a map), the extraction will lead to errors FAT32/exFAT.
- 🔴 Slot damage – mechanically extracting microSD without unlocking can deform contacts (relevant for Xiaomi 13 Ultra and other flagships with a dense build).
Android 12/13/14 (which is used in modern Xiaomi) has built-in protection: the system blocks the recording on removable media if they are connected as “portable storage”.
