Why won't my Mac recognize an external hard drive?
Mac's inability to recognize external hard disks are usually caused by connection problems, file system incompatibility or software failure. Solutions include: 1. Check the connection and power supply to ensure that the cable and interface are normal and try to connect directly; 2. Check whether the hard disk is displayed in the disk tool and try to mount manually; 3. Confirm whether the file system is compatible (such as exFAT or FAT32), NTFS requires third-party support, and Linux format requires special drivers; 4. Restart the device or reset NVRAM/PRAM; 5. If the above steps are invalid, it may be a hardware failure. In most cases, the above steps can be used to solve the problem.
