Your DX175 removable drive enclosure is now ready to use! If the drive inside is already formatted, it
can be used right away. If the drive is brand new or its format is not compatible with your computer, the

Formatting a drive will erase all data on the drive, so be sure to back up your data before
beginning this operation.
