    I used Samsungs on most of my S1, S2 and S3 upgrades, and had very good results. But my last few upgrades were all with the WD Green drives, also all good results.

    I'm definitely in the "if it saves me $50-100 I'll do it myself" camp, so I've never considered the Weaknees, DVR-Dude, etc., solutions.

    Of course, another option is to find a "friend" who is good with this sort of thing and have them hook you up. Then you get it for the drive cost, give or take....

    I don't think this question has been asked so let me go ahead and ask;

    Am i able to use a Dell Poweredge server to expand up to 4 drives at one time?
    My server takes sata drives and i have about 4 caddy's in there

    I bet with the linux CD it MIGHT be possible. The unix command "tee" takes input from a pipe and sends it two places--to a file, and to its standard out. If somehow the file was instead stdin going to a restore command, the same source "file" (the original TiVo drive) could be used to feed stdin to four restore commands simultaneously. There's also a "named pipe" functionality, where a "file" can instead be a pipe to some other process. I'm not familiar with the specifics of named pipes, though, but I got this from google on how to set up named pipes.

    What I'm thinking is something like this. Set up three named pipes, then three restore processes reading from them as their input. Notice each resotre is going to its own destination drive (a-d). That is:


    mkfifo /tmp/TiVo1 /tmp/TiVo2 /tmp/TiVo3
    cat /tmp/TiVo1 | restore -s 127 -nxzpi - /dev/sda &
    cat /tmp/TiVo2 | restore -s 127 -nxzpi - /dev/sdb &
    cat /tmp/TiVo3 | restore -s 127 -nxzpi - /dev/sdc &

    What I'm not sure of though is whether these backgrounded (the & makes them background processes) restore commands will just wait for input or if they'll error out. If they wait patiently for input, this should all work fine.

    The final step is to run this (syntax is from here), which will right to the three above restore commands as well as to this fourth one:

    Option 2.7 To copy everything from original size Tivo drive to bigger dual drives and expand capacity but limit the drive to 137GB:

    backup -qTao - /dev/hda | tee /tmp/TiVo1 | tee /tmp/TiVo2 | tee /tmp/TiVo3 | restore -s 127 -nxzpi - /dev/sdd



    ETA TESTED IT AS FOLLOWS. I'm almost certain this will work.

    $ cd /tmp
    $ mkfifo TiVo2 TiVo3 TiVo1
    $ cat TiVo1 | cat > dupe.TiVo1 &
    $ cat TiVo2 | cat > dupe.TiVo2 &
    $ cat TiVo3 | cat > dupe.TiVo3 &

    Not sure why not. Can you boot the mfslive CD in your server? If so you should be gtg.

    I don't know where to put all those commands or even where to start from

    It sees all the drives but still asks for only one drive to copy to,so i'm currently just doing one for now but if you can guide me with a tutorial,i'd give it a shot :)

    Ah, right--sorry.

    That CD does have an option to drop to a command line, you'll need to do that for this to work.

    There's not a "canned" menu option for a 1>4 drive upgrade like we're talking about.

    No, that was my test, duplicating one file four times simultaneously. Here's an example geared toward your TiVos.

    First, I'll assume that /dev/sda is your ORIGINAL TIVO hard drive, and that /dev/sdb /dev/sdc and /dev/sdd are your three BLANK hard drives. This is set up to make THREE identical copies of the one original drive (and expand to fit the new drive size). (The "$" I show here represents your prompt--your typing starts after that.) I also raised the swap size from 127 to 512.

    The mfsinfo command just examines a particular drive to see if it is a TiVo drive and if so how big. We do that before the restore on the original, then after on the other three.

    Note this can take HOURS AND HOURS, up to a day on slower systems. ANd doing it times three like this, give it a good long time. Your PowerEdge seems beefy enough, I would imagine this should not take over 12 hours, but that's just a guess.

    Note that each of the commands running (one backup and three restores, all running simultaneously) will be sending output to your screen. If you like you can add a "q" to the option letters (between the "n" and the "x", so "-nqxzpi", for instance) for all but one of the restores to quiet this down.


    $ cd /tmp
    $ mfsinfo /dev/sda
    $ mkfifo TiVo2 TiVo3
    $ cat TiVo2 | restore -s 127 -nxzpi - /dev/sdb &
    $ cat TiVo3 | restore -s 127 -nxzpi - /dev/sdc &
    $ backup -qTao - /dev/sda | tee /tmp/TiVo2 | tee /tmp/TiVo3 | restore -s 512 -nxzpi - /dev/sdd
    $ mfsinfo /dev/sdb
    $ mfsinfo /dev/sdc
    $ mfsinfo /dev/sdd

    Why?

    I say this every time it comes up only because newbs may not know the pain.

    Those external drives are NOT a good solution. Too many moving/fallible parts. And when it fails, you lose ALL recordings--there's no way to avoid that.

    Stick with 300 hours HD, that should do. If that's not enough, probably two tuners isn't either--get a SECOND unit.

    I'm fully aware of the fact that external drives are an -additional- fail point.

    I have three 2TB Premieres and one 2TB TiVo HD (not counting the 2TB Premiere and 2TB TiVo HD that I set up for my folks in another room).

    Guess what? They are all near capacity. So are all the 2TB drives that I have populating the SATA ports of my computer.

    Due to some odd problem that I have with the sound cutting out on analog channels, which neither Cox nor TiVo will help me resolve, I have to try and record as much as I can in digital, and 99% of that is only available in HD.

    I have a few "spare" 2TB drives laying around. Rather than use a true "external" drive, I'd like to just use an exact matching drive to the one I put inside, using a power brick to SATA power adapter, and a quality eSATA cable. I can build a "rack" for the drives to cradle in safely, out of sight, behind my tower of TiVos.

    Why? Because I want to. Isn't that enough, considering that it seems the obstacle to Comer's attempts at this has a solution now?

    I'm not a "newb". I've been lurking here for years, just not registered until recently. I figured being able to post was worth registering.

    Also, considering the cost of adding more cable cards for each additional unit, the CCI byte restrictions, and just how much I use my TiVos, I'll gladly accept the risk.

    I would have thought that you, of all people, would at least be interested enough in HOW weaknees got around a stumbling block that Comer couldn't (at the time), and if it can be replicated.

    From what I'm reading elsewhere, it has to do with a "register" of some sort.

    +1'ing ThreeSoFar is like giving my post a :thumbsdown:

    I'll let it slide, just this once. :D :p

    Read these posts about 4TB:

    http://www.tivocommunity.com/tivo-vb/showthread.php?p=8232305#post8232305

    then 2 weeks later:

    http://www.tivocommunity.com/tivo-vb/showthread.php?p=8251170#post8251170

    I would question the stability and reliability of a 4TB combo.

    Last year several vendors had the 4TB package, then they all removed them. Now Weaknees is offering one...... but noone else. I'd wait a few months and see if the 4TB is still available.

    I tried to add my 1TB Expander to the 2TB TP and it never did work. The expander did marry to the stock drive.

    It would be interesting to see the partition tables for the 4TB..... but at $530 I'm not all that interested.

    Don't get me wrong, no disrespect intended. I am also interested in the Weakness setup and what they did to overcome the earlier problems they and everyone else had with the 4TB option. I was +1ing the concept of adding the secondary fail point. I haven't to date (knock on wood...touching head) ever lost all of my recordings but I know I would be very upset if I did so I tend to move whatever recordings I can't live without to my computer (and then an external storage drive). If copy protection is an issue there is a way to mod a TiVo to overcome that, but that's a different thread.

    FWIW I believe another TCF member (aaronwt?) has built a Drobo type server to do something like you're considering...but with ├╝ber large terabytes of space. You might want to run a search.

    Me? I'm just waiting for the 3TB single drive upgrade...then 4TB...then...;)

    Frankly, I didn't even look at your post count or TCF sub date. I assumed you were not a newb, but lots of newbs do use this thread as a resource and I wanted to save them that pain. I assume you're not suffering from dissociative disorder--the plural was also not directed at you.

    FWIW, we added a couple free (non CC) HD tuners to our mix by putting an indoor antenna on our top floor Series 3 to give us a little more HD space on the OTA networks. We record and watch a TON, more than anyone I know, and since going to 2TB haven't come close to filling them. We have five dual tuner HD capable lifetimed TiVos (2S4, 1HDTiVo, 2S3), all but one at 2TB, the other at 1TB. You're the first to eat up more space than us that I've heard of.

    And I differ from Rich here--I am not[/i] interested in any solution dealing with an external drive specifically because it introduces too much risk to losing content. I don't want our "customers" on this thread to ever see just that side of the equation and be disappointed when they run into failure because of it, so I will take the opportunity your post and others like it presents to point out that fact.

    FWIW I still agree. I'm not interested in an external solution either...only in what they did to overcome prior problems. That info might be adapted to allow us to use something larger than the current 2TB limited internal drives. 3TB drives are already out there and IIRC 4TB's are just around the corner.

    We're also in the same boat...it will be quite a while before our 2TB PXL hits the wall. We also use our Series3 as a quasi-three and four tuner option but mostly for those fairly rare occasions when there are more than two programs we want to record on in the same timeframe.

    I read those back when they were originally posted.

    It's still a good reminder, though. I didn't jump on the Comer JMFS bandwagon until after the second revision was out, and after it had been out for long enough for others to hit max capacity and verify no disasters awaited.
