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?

Why is the writing speed of my StoreJet extremely slow when the reading speed is normal? Why can't my multimedia player, TV or DVD player detect my StoreJet (external-HDD)?
