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 What should I do if the transfer speed of my StoreJet is too slow? Why it is not recommended to remove the product casing or disassemble the product? When transferring a large file, I get an error message saying that "the disk in the destination drive is full...," but my disk is not full. Why can't I transfer this file?
