Step 5. Unable to read U disk contents
If your phone does not read the USB disk, you can:
1. Format u disk. (The following needs to be done on your computer)
1) Right mouse click on the U disk letter Select "format."
2) in the file system, select FAT (Default) or FAT32.
3 after selecting, click "Start" below. (For example, "FAT (Default)")
Note:
1) before you format a U disk, be sure to back up the useful data first.
2) When formatting, the quick format of the hook will be canceled to prevent U disk data can not be completely removed.
2. Because the mobile phone to the U disk capacity has the largest support limit, recommended to replace a U disk attempt.
3. If the current is too large, such as tips, we recommend replacing a low power consumption u disk.
