How 2...Expand the storage capacity of your cable DVR
TiVo and satellite DVR boxes may also support hooking up an external hard drive. The following instructions are based on the Scientific Atlanta Explorer 8300HDC, but the process should be similar for other Scientific Atlanta cable DVRs.
1. Get an external hard drive that has an eSATA connection and an eSATA cable. Some compatible drives include the Western Digital My Book Home Edition Series ($130 to $300) and the Seagate FreeAgent Pro series ($120 to $200). Western Digital sells a hard drive specifically for expanding your DVR's storage (My DVR Expander, $170, includes eSATA cable). Seagate plans to release a similar product later this year. For cables, check CompUSA or look online.
2. Note the amount of space used and/or remaining on your DVR and write it down. Turn your DVR off and unplug it.
3. Connect the power cord to your external hard drive and plug it in. Do not plug it into a power strip or other power source that can be turned off with a switch. If possible, plug the drive into an uninterruptable power supply (UPS). Connect the hard drive to the eSATA port on the back of your DVR box using the eSATA cable. Plug the DVR in and after it finishes booting up, turn it on.
If you get a message that your drive needs to be reformatted, follow the instructions to reformat the drive.
4. Check the capacity gauge on your DVR. If there is more storage space available than before, the drive is working properly. If not, or if your recorded shows do not appear, turn off and unplug the DVR and hard drive and repeat step 3.
5. The next time you record a show, it will be saved to whichever device has more room available, the external hard drive or the DVR. You cannot choose where to store a show. Do not unplug or disconnect the hard drive without unplugging the DVR first.
You can't unplug your hard drive and hook it up to another DVR or computer to watch recorded shows. If you get a new DVR box, you can reformat your hard drive to work on the new box, but you will lose all of the shows you recorded with the old DVR.
Like other external hard drives, there is a possibility that you will lose your data, or in this case, your recorded shows, if there is a power surge.
