Re: [DVR] External DVR Storage
I have been around long enough to know that people do not usually like "cross posting" in different threads , but I have done so here as I think this info will be of great interest to those that want to add a external drive to their Motorola DCX3400 DVR and also people that do not want to buy the "official" (and more expensive) extender.
OK , so we got the A30 Guide update here in NE Philly (19111) around Tue 22nd 2013.
I have Motorola DVD DCX3400 , it is not listed on the "supported" list of DVR's that Comcast issued a while ago , but still thought I would give it a try after reading the other posts at this thread and some others.
I used a old 1TB WD Green Series SATA 11 hard Disk that I had laying around my workshop , and also a $30 USB Enclosure that also has a ESATA port on it.
All works Perfectly , as soon as the drive spun up , a message came on screen and asked me if I wanted to format the External drive , I said YES , and this took about 10 seconds. My available space for recordings on the DVR then dropped from 47% to 9%!
I then installed a 2Tb Seagate Hard disk into the enclosure that I also had spare and my available space went from 47% to just 5%!
All new recordings from that point on, were made to the New 1.0TB drive , if this drive is switched off and you try and play those "new" recordings , a message on screen prompts you to switch on/connect the external drive (it says the Hard disk model number).If you do this, the recordings then play perfectly.
All previous recordings you made before you installed the external drive are available when the external is switched off and play perfectly.
So to conclude:
1) You do not have to use the WD Extender "approved" external drive - you can just use a El cheapo external enclosure as long as it has a external ESATA port on it. I tried it with both a 1.0TB WD Drive and a Seagate 2.0TB Drive , both worked perfectly.
2) All works perfectly (for me anyway) as along as you have the New A30 guide on the Motorola DCX3400.
3) If the External hard disk breaks down or you have to swap out the main DVR for any reason, you will loose any recordings you have made on the external hard drive (as the recordings made on the external are tied to the serial number of the DVR) - but that's just the risk we take I guess.. but its a risk I am very willing to take,in order to have 2.35 TB of recording space compared to the pathetic 350gb I had before.. in my case this cost me very little as I had the hard disk and enclosure laying around doing nothing.
Please feel free to ask any questions...
Glad everything is working for you. I do feel I have to caution others that everyone's mileage may vary and not everyone may have the same quality of results. The AV hard drives from Western Digital and Seagate (such as the one built into the DVR) are designed specifically for audio and video use and constant buffering and spinning 24/7 so the use of any old hard drive not designed for said abuse may fail faster or not have the correct spin speed. From what I've discovered the Seagate AV drives spin at around 5900rpm and the Western Digital AV drives are dynamic.
