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.

4.   Disks
Use only supported disks in your ReadyNAS storage system. If you use non-supported disks, 
NETGEAR Technical Support will not provide assistance. For a list of supported disks, see 
theNETGEAR Hardware Compatibility List at 
http://www.readynas.com/hard_disk_hcl.
For information about configuring disks on your ReadyNAS storage system, see the ReadyNAS 
RAIDiator 5.3 for Home Software Manual
, which is available at 
http://www.readynas.com/documentation. 
This chapter includes the following topics:
•     Previously Formatted Disks 
•     Adding a Disk 
•     Failed Disk Notification 
•     Replacing a Disk

 ReadyNAS Duo v2 and NV+ v2
Previously Formatted Disks
You must take care when using previously formatted disks in your ReadyNA\
S unit, as 
described in the following table.
Table 1.  Previously Formatted Disk Precautions
Unit StatusPrecaution
ReadyNAS unit has no disks 
(diskless) Turn the unit off and insert the disk as described in 
Diskless Units on 
page   8. Then, perform a factory default reboot as described in Boot Menu 
on page
  16.
Note:
  This process erases all data and reformats the previously formatted 
disk to X-RAID2. If you want to preserve the data on the disk, you must \
move the data to an external drive before using the previously formatted\
 disk 
in your ReadyNAS unit. 
You cannot use previously formatted disk in your unit without following \
this 
process. For example, if you try to use a disk that was formatted for a \
Duo 
v1, an NV+ v1, or a Windows operating system, RAIDar displays a “Corr\
upt 
Root” error message. 
ReadyNAS unit is operating with 
one or more disks With the unit running, insert the disk in an empty disk bay as described\
 in 
Adding a Disk on page
 28. The unit automatically formats the disk in the 
same format as your existing disks. 
Note:   This process erases all data on the previously formatted disk. If you 
want to preserve the data on the disk, you must move the data to an exte\
rnal 
drive before using the previously formatted disk in your ReadyNAS unit. \
Previously formatted disks must appear on the NETGEAR Hardware Compatibi\
lity List, 
which is available at http://www.readynas.com/hard_disk_hcl. 
						

							Disks28
ReadyNAS Duo v2 and NV+ v2 
Adding a Disk
You can add a hard disk to an empty disk bay. You do not need to shut do\
wn your unit before 
adding a disk.
If you are adding a previously formatted disk to your Duo v2, NV+ v2, se\
e the precautions in 
Previously Formatted Disks on page
 27.
To add a disk:
1. Press the disk tray release latch. 
The tray handle pops out. 
2.  Pull out the disk tray, place the new disk on the tray, and assemble the\
 disk and tray 
with the screws that came with your unit.
Make sure that the hard disk connectors face the interior of the disk ba\
y.

3. Slide the disk tray back into the unit and press the handle to secure the disk.
The volume automatically synchronizes with the new disk in the background. This might 
take several hours, depending on the disk size. You can continue to use your ReadyNAS, 
although access is slower until the volume synchronization finishes. You are notified by 
email when the process is complete.
If you are adding disks to a diskless unit, see the ReadyNAS RAIDiator 5.3 for Home 
Software Manual, which is available at 
http://www.readynas.com/documentation, for 
information about using RAIDar to discover your unit on your local area network for the 
first time.
Failed Disk Notification
If a disk fails, you are notified by email. Email alerts must be set up for notifications to be 
sent. In addition, the ReadyNAS Dashboard provides information about the failed disk. 
NETGEAR recommends replacing a failed disk with the same disk model. Use the 
ReadyNAS Dashboard to determine the disk vendor and model used in your unit. 
For information about setting up email alerts and using the ReadyNAS Dashboard, see the 
ReadyNAS RAIDiator 5.3 for Home Software Manual, which is available at 
http://www.readynas.com/documentation.
WARNING!
No matter how many hard drives are installed in your unit, ensure 
that all drive trays remain in the drive bays to maintain adequate 
airflow.

ReadyNAS Duo v2 and NV+ v2 
Replacing a Disk
In the case of a failed disk, the unit provides email alerts and status \
messages about the 
need to replace a disk. ReadyNAS supports hot-swap bays, so you do not n\
eed to power 
down your unit when replacing a disk.
If you are replacing a disk with a previously formatted disk, see the pr\
ecautions in 
Previously 
Formatted Disks on page  27.
To replace a disk:
1. Press the disk tray pull release latch. 
The disk tray handle pops out.
