Your ReadyNAS or ReadyDATA storage system offers several boot modes for restarting or troubleshooting.

Your storage system has the following boot modes:

  1. Normal. Initiates a normal boot process, just like booting using the Power button.
  2. Factory default.

    WARNING: The factory default reboot process resets the unit to factory settings, erases all data, resets all defaults, and reformats the disk to X-RAID.

    • RAIDiator. Initiates a short disk test that takes approximately five minutes, then begins a 10-minute time-out period waiting for RAIDar. During the 10-minute time-out period, the system can be powered off safely without causing any data loss. After 10 minutes, the factory default process begins. If you launch the factory default boot mode with RAIDar during the time-out period, the factory default process begins immediately.
    • ReadyNAS OS 6. Initiates a small disk test that takes less than a minute, then begins the factory default process immediately.
  3. OS reinstall. Reinstalls the firmware from the internal flash memory to the disks. The OS reinstall boot mode can be useful when the system crashes and corrupts some configuration files. OS reinstall boot mode also resets some settings on your unit, such as Internet protocol settings and the administrator password, to defaults.
  4. Tech support.

    WARNING: Use the tech support boot mode only when instructed to do so by a NETGEAR Technical Support representative.

    Boots into a low-level diagnostic mode.
  5. Skip volume check. (RAIDiator only)

    WARNING: Use the skip volume check boot mode only when instructed to do so by a NETGEAR Technical Support representative, otherwise data loss might occur.

    After a system crash, the system tries to scan and fix the volume using a file system check. If several problems are found on a disk, this process can stall, causing the system not to boot. You can use this option to skip the scan and let the system boot.
  6. Memory test. Performs a memory test. The pass or fail result is reported using the unit's LEDs. Contact NETGEAR Support to interpret memory test results.
  7. Disk test. Performs an offline full disk test. This can take 4 hours or more, depending on the size of your disks. Any problems are reported in the RAIDar discovery tool.
