Boot Menu
Use the boot menu to restart or troubleshoot your ReadyNAS unit. Your unit has the following 
boot modes:
•     Normal. Initiates a normal boot process, just like booting using the Power button. 
•     Factory default. Initiates a short disk test that takes approximately 5 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, or if you select the factory default option with RAIDar during the time-out period, 
the factory default process begins. 
WARNING!
The factory default reboot process resets the unit to factory 
settings, erases all data, resets all defaults, and reformats the disk 
to X-RAID2.
•     OS reinstall. Reinstalls the firmware from the internal flash to the disks. Use the OS 
reinstall boot mode 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. 
•     Tech support. Boots into a low-level diagnostic mode. Use the tech support boot mode 
only when instructed to do so by a NETGEAR Technical Support representative.
•     Skip volume check. 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. Use this option to skip the scan and let the system boot. 
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.
•     Memory test. Performs a memory test. The pass or fail result is reported using the unit’s 
LEDs. Contact a NETGEAR technical support representative to interpret memory test 
results.
•     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.
