Creative Zen Micro 5GB In-depth Review
 

Finally, within the extras category is the ability to use the Zen Micro as a USB Mass Storage Device for carrying along your personal files. However, unlike competing players, the Zen must set up a separate partition specifically for data, and this can only be set as 128MB, 256MB, 512MB, 1GB, 1.5GB or 2GB. When using the latest beta firmware, a 4GB option is also available. While not as accurate to the file as we'd like, using a second partition for data may just be a requirement of Microsoft's PlaysForSure seal.
