Starting in v2.5.3, the HDD, MU, and IMU formatters will be usable in the trial version. They are normally features only usable with a paid license.

Why?

A lot of people get confused and sometimes think that the formatters can make any device usable on the Xbox 360 console. A lot of people purchase FATXplorer with that in mind, only to be disappointed and request a refund. In an effort to eliminate false purchases and to alleviate confusion, it has been decided that these 3 formatters will be made free.

New customers are now free to take advantage of the formatters during the 7 day trial period. However, once that expires, you will still need to purchase a license to use them, but they are tools you should only really need once.

The USB formatter will remain a paid feature.
