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 with the unconfigured disk, and how to partition my StoreJet (external-HDD) into several disks? Will the StoreJet be damaged if it is not securely removed? Why it is not recommended to remove the product casing or disassemble the product? Technical Support If the answer can't help you, you can contact the Tech Support Department Get Started
