With the Western Digital My Book AV DVR Expander for TiVo boxes, you can increase the recording capacity of your TiVo box.
The Western Digital My Book AV DVR Expander is available in a 1 TB size. Once the expander is plugged into the eSATA port on your TiVo box, it will be "married" to that box. The 1 TB expander will add over 140 hours of HD recording space (or over 1200 hours of standard definition recording space).
The DVR Expander can be used with:
Note: The Western Digital My Book AV DVR Expander cannot be used as a mobile storage device to transport shows from one TiVo box to another (or to another device). If a DVR Expander is disconnected from the TiVo box to which it is married, and formatted by another TiVo box, all or most of the recorded content on the original TiVo box and all of the content on the DVR Expander will be lost.
In order for you to connect your DVR Expander, you must first have a supported TiVo box, listed above.
Note: Some models of the 'My Book AV DVR Expander' from Western Digital include a USB cable in addition to the eSATA cable, but only the eSATA connection is supported for use with the TiVo boxes.. If you have connected a DVR Expander using the USB connection, disconnect the USB cable and follow the steps using the eSATA cable.
Follow these instructions when temporarily disconnecting the DVR Expander (to clean or move your entertainment center, for example)
CAUTION: Always unplug the power cord from the electrical outlet before disconnecting the AC adapter from the DVR Expander.
Follow these instructions to reconnect your DVR Expander after temporarily disconnecting it.
CAUTION: Do not reconnect the power to the TiVo box with the DVR Expander disconnected. This will cause you to permanently remove the expander and lose all or most of your recordings.
Under normal operating conditions, there is no reason to remove the DVR Expander. Removing the expander does not allow you to play your recordings on a different TiVo box. Because each recording is distributed equally between the TiVo box's internal drive and the expander, you cannot gain additional storage by using more than one DVR Expander. You should only remove the DVR Expander if you wish to stop using it.
