Status: Unix: Works Mac: Works (but most mac's don't have SATA ports which then requires a modern USB-Sata adapter.) Windows: VHD available...Testing new cloning software... Requires: 4TB hard drive Tivo Roamio Computer with a free Sata or eSata port USB docks may work, but not recommended (many older USB docks have bugs that don't go up 4TB) UNIX (Linux*/BSD/Mac) Command Line Installers The autoinstaller will search for drives for one with a Tivo signature**, download the image from the Net, and overwrite the drive with the image. * If needing a liveCD, knoppix has been tested ** If the drive is missing a signature, booting it in a Roamio will add a signature, or you can manually add one with a hex editor [0x1492] PC / Mac side: 1) Connect Hard Drive to Computer (disconnect other HD's with important data) 2) on PC: Boot from linux CD or USB stick on PC's. on Mac: boot normally into OS X. When asked to "Initialize" an unknown drive, just say No / Ignore / Cancel. 3) Open Terminal, by clicking Terminal icon 4) Download Auto Installer, by typing at prompt: wget "http://tiny.cc/c6r5gxA/autoinstall.pl" ( or wget --no-check-certificate "http://tiny.cc/c6r5gxA/autoinstall.pl" ) Another option is: curl -L http://tiny.cc/c6r5gxA/autoinstall.pl -o autoinstall.pl Enable execution by typing: chmod +x autoinstall.pl 5) Start installer. On PC Linux or Apple Mac run: sudo ./autoinstall.pl This will ask for the account password. Lots of text will fly by, just follow along a best you can. The most important thing is to Check that it chooses the right drive. (you did already disconnect all your important drives, right?) It'll ask before making permanent changes, then when it starts writing... 6) Take a break to let it finish ~20mins on USB2 Less on USB3 or Sata More on USB1 Alternate 4) Image + Basic Installer: wget --no-check-certificate "http://tiny.cc/c6r5gxB/4TBr1.tgz" bypasses safety mechanisms, so know what you're doing or don't use.. Tivo Roamio side: 7) Connect drive 8) Turn on Power to Tivo 9) Wait until Guided Setup (takes about 4 mins for first boot) 10) Celebrate and Donate what you think it's worth. Known limitations: No data is migrated over (pytivo/kmttg backups should work) Cable Card will likely need to be re-paired, but in a smaller number of cases, this did not apply Not supersized Found Tivo bug, variance in fsck mount frequency, should be inconsequential Donations here: paypal or amazon-e-gift-card: marked @ gmail.com bitcoin:1Hvpf8qV8UJ8SS33QJ6VskggAStQQDnYp6 Credits and Thank You to jmbach - for extensive testing and lots of direction ggieske - for tricky MFS answers and eboydog - for initial motivation Terms: Image and Installer Copyright 2014.
