First check whether the physical connection between the USB flash drive and the Mac is normal, try changing the port or removing the adapter; if the connection is correct, enter the access preferences and ensure that the "External Disk" is displayed in the desktop and sidebar; if it is still not recognized, open the Disk Tool to see if the USB flash drive is detected by the system. If it is displayed, click Mount. If it is prompted to be damaged, you can run first aid repair; if the file system is incompatible (such as NTFS), you can format the USB flash drive to exFAT or MS-DOS (FAT) format in Disk Tool (note that this operation will clear the data); if the above method is invalid, run the diskutillist command to find the USB flash drive device identifier through the terminal, and then use the diskutilmount command to manually mount it.

Answer: To use Windows built-in EFS to encrypt folders, you need to right-click the folder → Properties → Advanced → Check "Encrypt content to protect data" → Apply and select the encryption range. At the same time, you must back up the EFS certificate and private key to prevent data loss. EFS relies on user account security and only supports NTFS. It is suitable for stand-alone privacy protection, but is not suitable for multi-user sharing or high-security threat environments. Compared with traditional password encryption, EFS is integrated with system login, without repeated input of passwords, but the account password is securely bound. For higher security requirements, you can choose third-party tools such as BitLocker full disk encryption or VeraCrypt. When backing up the key, you should export the PFX format certificate and set a strong password to store it in a secure location.
