Understanding the System Diagnostics Boot Menu
This section introduces the system diagnostics boot menu.
1. Boot Menu Enabled: Use the Reset button to scroll through the menu to select an
option within 3 seconds. After 3 seconds the boot menu defaults to Normal Boot.
2. Normal Boot: Perform a normal boot.
3. Factory Default: Reset the ReadyNAS back to its Factory Default state, erasing all data on
the disks. This option can be used to change between X-RAID2 and Flex-RAID mode.

wiping out any data you might have on the unit.
