Product Compatibility.
Hitachi's new 4GB Microdrive is designed to the Compact Flash Type II industry standard and is compatible with a wide variety of devices that accept CF+ Type II media. The 4GB Microdrive is formatted at the factory using the FAT32 file system to remedy the 2GB limitation of the FAT16 file system. Therefore, when used in a digital camera, the camera must support a FAT32 file system.
