This update adds support for IDE and SATA drives (that are formatted to fat32) this allows for persistent storage over drives and gives the system some use other than just a showcase :D The user can switch between drives in the explorer by clicking on the dropdown and then clicking any drive letter ( A:, B: .. C:) this list dynamically expands on how many drives there are in the system. In the cmd the user just types A:, B:, C: etc to switch to that drive.
