Replacing a Failed Disk
When a disk fails in your ReadyNAS device, you are notified of the failure by e-mail. The failed
disk location can be seen in the FrontView status bar at the bottom by selecting Status > Health.
On the front of the ReadyNAS device, a failed disk is identified by an amber LED. The left most
LED is disk channel 1; the next one is disk channel 2; and so on. Take note of the failed channel.

Choosing a Replacement Disk

On the main menu, select Status > Health. Take note of the disk vendor and model used in your
ReadyNAS. It is best to replace a failed disk with the same disk model. Contact the disk vendor,
and arrange to have the disk replaced if the disk is still under warranty. A disk RMA from the
vendor requires that you provide the serial number of the disk. To locate the serial number, open
the case and take out the failed disk (see the following sections for replacement instructions for
your disk model).
If the disk is no longer under warranty, you can obtain a disk of the same capacity or larger from
your ReadyNAS retailer.

Replacing a Failed Disk

When a Disk Status LED blinks slowly, it is an indication of a failed disk. ReadyNAS supports hot
swap bays, so there is no need to power down the device.
To replace the disk:
1. Open the disk bay door.
Note: Be sure to check the Hardware Compatibility list on the NETGEAR support site for
a list of disks that have been qualified for the ReadyNAS Pro to assure that you use
a suitable disk.
