What are some functional differences between the Windows and the Mac versions of Transcend Elite? Category : Software / Firmware / Applications Note: 1. To have the external hard disk support both Windows and Mac operating systems, we recommend formatting the hard disk into FAT32 or exFAT format. 2. The disk lock/unlock function for MacOS version is still under evaluation. Is the answer helpful? Related Why does the disk failed to be lock/unlock when employing Elite's "disk lock" function? If the files you hope to back up contain those that are not allowed to be backed up, a warning message will pop up from Elite and the backup task will be interrupted. Why do files occupy more disk space when saved to flash drives/external hard drives/solid state drives?
