    I call BS on tweaking and optimization regardless of optional command sets being disabled. If the drive could tweak and optimize without them, they wouldn't be optional. Don't forget how much AV we do on computers using non-AV drives. Clearly, AV can work (to a point) with any platter drive.

    Might an AV drive be better suited to the way TiVos write in long contiguous blocks, even though the AV command set is disabled? So far, I have found no proof of this, but haven't ruled it out. The only optimization I dare to suggest is the lifespan being extended due to PWL, on the AV drives that have it. The only thing I can't verify is if the PWL is independent from the optional modes (can't verify it makes the platter sweeps while not using the AV extensions).

    My SD channels are 3.89MB/s and my HD channels are 11.36MB/s on the better channels. Some are a fraction lower, but the only channels I have that are significantly lower are music channels, 0.38MB/s SD & 0.67MB/s HD.

    Your bandwidth calculations are off, and your interpretation of the WD specs and marketing materials seem off.

    On todays Hard drives all you should look for is low power and at least 5400 RPM, they will all work in a TiVo, with the delete folder filled up you are using the total drive very quickly, unless you deleting stuff from the delete folder.
    I think you guys are over thinking this hard drive issue, just my option.

    I use KMTTG, so being so easy to clear my RD folder (Ctrl-A & Del key), I do so. It does seem to make the menus a little zippier, and I notice fewer glitches in recordings.

    I've found the speed in which the data in System Information fully populates is a very reliable indicator of anything loading or slowing the drive. There's always a momentary delay for some data to fill, but it gets longer if I don't clear RD.

    If said data takes more than 3 seconds to populate, and the TiVo is not busy recording, there's a good chance that there is corruption, and it's time for a KS 57/58. If that doesn't fix it I tend to find sectors erroneously marked as bad.

    P.S. Are you trying to balance things out, since I tend to always comment anywhere you bring up the "any low-power profile 5400 RPM drive will do" opinion? ;)

    I will have to start using KMTTG as I did not know about the quick delete od the DF.
    Over the years I have used many different Hard Drives in TiVos and never found any problems (other than the park crap with WD) with any brand, but I do use WD most of the time.
    If somebody has had any (more than once) bad experience with any brand of hard drives (not SSD) for TiVo use I would like to know.

    I put a Samsung HD203WI in my TiVo HD a few years ago. That was an upgrade from a 1 tb Western Digital green non-AV drive. The HD203WI developed a few bad sectors and was replaced by a HD204UI.

    The only other drive to have issues was one of the original drives (WD1600) in a secondhand Tivo HD. There were no bad sectors in the first 40% or so of the drive and then there was a wall of bad sectors that caused both the WD diagnostic and HD Tune Pro to quit halfway through the test.

    On top of the quick bulk deletion of RD contents (happens instantly on an uncorrupted drive that is operating properly), is the ability to bulk-restore from RD. The latter takes about a second per recovered item, which is still fast.

    I once quickly bulk-cleared RD, then used KMTTG to nearly instantly bulk-send all the recordings of a half-full 3TB drive drive to RD. I was then rather quickly able to bulk-recover all of them, clearing-away any KUID flags from recordings, bringing the TiVo ecosystem to a much better state.

    Other than watching what in on my TiVo, there are very few operations that I use my TiVo to do anymore. KMTTG is just so much easier, once you get past the minimal learning curve.

    I also found that I can run two instances of KMTTG, and put the windows (each one displaying a different TiVo) side-by-side, making it easy to do a great deal of things quickly, in one sitting, rather than spending hours/days running around to multiple TiVos.

    I was able to identify a problem drive by comparing the time it took the same number of operations to process between three TiVos. Pulling that drive for testing with a PC proved it was a slower-operating drive (non-acceptable read timings).

    I've spent at least 30 hours over a few days digging into non-marketing information on drive technologies and feature set standards. I have a long way to go, and am taking a break to insure I'm retaining what I should be.

    So, more to come, if my head doesn't explode first. I'll probably make my own thread for that, to try and stop diluting/congesting other threads.

    To use KMTTG on a Windows 7 desktop computer do I need any other software like TiVo desktop software ??

    I just installed it and the only thing you need is 32 bit Java. It does help if you make a shortcut to run it as an administrator. Making javaw.exe to run as administrator did not work well for me when trying to install kmttg service. Plus I did not want it to run as an administrator for all Java programs.

    I just installed it also, works great, will have to look at all the options but deleting the delete folder was easy. I had no Java problems

    FYI: Besides the program itself, there's a KMTTG service that I have found no need to have running (it's optional), if you aren't looking to automate downloading and processing of recordings. There's also an optional tools package full of codecs and processing tools that can be left-out if you want the smallest footprint.

    The best place to ask questions and get advice is here: http://www.tivocommunity.com/tivo-vb/showthread.php?t=387725

    Thanks for the info and link. The service is what I needed administrative privileges to install, start, stop.

    No problem. Something else anybody new/returning-to using KMTTG needs to know is that each TiVo needs to have the Settings & Messages> Settings> Remote, CableCARD, & Devices> Network Remote Control option set to "Allow network-based remote controls", as opposed to the default of "Do not allow", IIRC.

    Like many others, I'm cautious of what I'll install, mostly due to how deep some things get their hooks into the Windows ecosystem, and how many startup services they add (Like TiVo Desktop). When I finally tried, it didn't take long for me to realize how much easier it makes things, and that calling it a "replacement or alternative to TD/TDP" just doesn't do it justice. If it could push files to TiVos without relying on PyTiVo, and queue-up TiVo->TiVo transfers, it would be the one true TiVo "Swiss army knife". I still see a lot of people who are not willing to trust it, or just refuse to try it. That's a shame (for them), which I didn't take long to realize myself.

    The only issues I have ever had with it were related to some Java updates that crippled it (and some other things requiring Java). Other reported problems are usually due to outdated Java versions, and/or not keeping KMTTG updated (used to require effort, now has check for update function), that network remote setting, TiVo mind/middlemind server issues (or something TiVo breaks with an update), and/or failing to enter the TiVo account login name/password (required for some functions that access TiVo's servers).

    Note of caution: KMTTG remembers what TiVo each function tab was last used for, within and between sessions, requiring the user to pay attention to what TiVo is selected when switching between function tabs, or one could apply an operation to the wrong TiVo. I still make this error, which is why I don't allow others in my home to use it. I don't want careless use to mess up my TiVo with an operation they intend for another.

    Applying a function to multiple TiVos is as easy as leaving the same function highlighted, selecting another TiVo, and pressing one button to apply the same function.

    The functions that help keep this thread-drift partially on-topic are how KMTTG can back up SP lists, which can be restored to any TiVo (in the exact order they are listed, and regardless of having any guide entries), and backup/restore other things. This makes it a must-have tool for those changing a drive (upgrading, or replacing a failed drive).

    I applaud telemark and the other members, who made the "4TB Roamio Image community edition" project this thread is for, possible and available. For all the work and effort involved, there's not much on-topic content here. I still see a great deal of posts around the forum stating that 3TB is still the maximum true DIY size, and that weaknees is the only way to get 4TB. The news that this option exists, isn't travelling fast, or far, AFAICT. Perhaps somebody should consider reaching out to the mods/admins to allow signatures with the news and a link to this thread...

    OTOH, anything that helps keep this thread fresh in the New Posts list, increases awareness of it.

    Is the 4tb image ready for prime time yet? Has the Windows prep been worked out? I'm not a Linux guy but at the worse will a Linux boot CD work at the least ?

    Image is fine. I have a few downloads, and 0 complaints.

    There's a VHD file, that's hypothetically for Windows. But as far as I know nobody has confirmed an imager that's known working with it.

    It is known for the dedicated, that iBored, tar, and gzip could be used.

    Linux Boot CD's work fine. I've tested knoppix myself.

    I created a VHD but the restore process takes hours as it restores the whole 2TB image to the drive. I do not have anything that ignores the zeroed out sectors as that is what most of the image is. Best bet is use the Knoppix CD or in Windows use iBored to write the images to the pertinent areas of the drive. You will be done in less than 10 minutes.

    I use command 'wget --no-check-certificate "http://tiny.cc/c6r5gxA/autoinstall.pl"' because without command --no-check-certificate, it shows error: the certificate of 'dl.dropboxusercontent.com' is not trusted and error: the certificate of 'dl.dropboxusercontent.com' hasn't got a known issuer.

    But each time, I use command chmod +x autoinstall.pl and ./autoinstall.pl, it will show the same error: the certificate of 'dl.dropboxusercontent.com' is not trusted and error: the certificate of 'dl.dropboxusercontent.com' hasn't got a known issuer.
    What should I do to solve this problem?

    Something's causing a HTTP to HTTPS redirect, give me a few minutes to test it.

    What OS are you using?

    Dropbox must have changed their backend, cause I know I tested that version before.

    In any case, I edited the script to skip the internal SSL check, so if you start from the beginning, it should not be a show stopper anymore.

    Thank you for reporting it.
