## Clearing Data Drives

In general, storage media does not need to be formatted after an initial format when receiving the system. Data can simply be cleared from the device. For USB drives, simply delete everything on the drive once downloaded. For Sony SD cards, delete only contents inside the DCIM folder. For microSD cards, delete only mission data, leaving config files, etc. intact.
