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 storage system, 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 a
NETGEAR technical support representative instructs you to do so.

Volume read only. Mounts a volume as read-only. Use this option when you are attempting to rescue
data off a disk during a disaster recovery.

Memory test. Performs a memory test. The pass or fail result is reported using the storage system's
LEDs. Contact a NETGEAR technical support representative to interpret memory test results.

Test disk. Performs an offline full disk test. This process can take four hours or more, depending on
the size of your disks. Any problems are reported in the system logs. For more information about viewing
the system logs, see the ReadyNAS OS 6 Software Manual, which is available at
