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 How can I format my StoreJet to exFAT file system under windows XP OS? Why do I receive a "USB Hub Power Exceeded" error message when I connect my StoreJet (external-HDD) to my computer? If I use the Transcend Elite for Windows to encrypt files in my external hard drive, can I decrypt them when connecting the drive to a Mac?
