Replacing a Failed Disk
When a disk fails in your ReadyNAS Duo 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 Duo 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. Take note of the failed channel.

Ordering a Replacement Disk

On the main menu, select Status > Health. Take note of the disk vendor and model utilized on your
ReadyNAS Duo system. 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 Duo retailer.

Replacing a Failed Disk on the ReadyNAS Duo

When a Disk Status LED blinks slowly, it is an indication of a failed disk. The ReadyNAS Duo
supports hotswap bays, so there is no need to power down the device.
