Fixed USB Device Not Recognized

Highlight before Troubleshooting
1) Ensure you have Administrative Privileges: diskpart requires administrative permissions to run.

2) Check Disk Connection: This method will not work if the thumb drive is undetectable by Windows. If it is undetectable, try the steps at the link below to ensure Windows detects and recognizes it.

If it is still undetectable, maybe the drive's chips are faulty. Just change to a new USB drive if your data is not important. Otherwise, seek a professional data recovery service centre to retrieve data.

3) Double-Check Disk Selection: This method will delete all data from the selected drive. Always verify that you selected the correct disk before performing operations to avoid losing data.

Types of file system
1. NTFS: The drive is viewable in Windows and MacOS, but you can't edit the file on Mac. (format fs=ntfs quick)
2, Exfat: The drive is usable on Windows and MacOS. (format fs=exfat quick)
3. Fat32: The drive is usable on Windows and MacOS, but it limits the size of each file to 4 GB and below. (format fs=fat32 quick)
