Is anyone working on DIY 4tb drive upgrade and is it worth starting a new thread here ? I must say that after having 3tb of storage in my Roamio, it's somewhat overwhelming and I do see having 4tb of storage as being unmanageable. I would like to figure this out simply as a challenge to overcome but in a practical day to day operation, having that much recording storage is crazy! I'm not a hex editor type but with the recent thoughts of the image copy distribution of the drive that came up, I have an idea I would like to throw out to perhaps get things started in a legit manner rather than just copying someone else's work. Can't tell me that there are only one or two people on the Internet (other than Tivo themselves) that can figure this out! My out of the blue idea: Has anyone done a sector copy of stock Roamio drive and then applied it to a 4tb drive? I plowed though the big Roamio drive upgrade thread and saw what happens when you put a raw 4tb drive in and the box tries to format it but rejects it but, what would happen if the basic unreadable image of a stock drive was written to the beginning of a 4tb drive, could that possibly overcome that initial rejection? I'm curious what something like Clonzilla could do.... It's my thought that perhaps there is no partition on the Roamio drive and when the box boots up, it looks for the drive and reads raw data off the drive at the beginning of the drive which contains "is this good" drive and if so the OS continues the boot and initialization process until everything is loaded. This is just my thought as unless I'm wrong, all conventional attempts to read the partitions in the conventional manner has failed, there must be a completely new and different file/data structure in place which would indicate a raw, most likely encrypted, data being written to the drive in a Stream like process. Another issue which I mention in another thread which is a possible clue, those who have the 4tb drive solution are offering it for each Roamio model, their drive kits they offer don't appear to be a universal solution but each prepared drive only works in the model the buyer intends to install the prepared drive in. DVR Dude is very explicit in his eBay description that his kits can't be installed in a different Roamio model than specified. That implies there is some basic required identifying information on the drive that is required to start a successful identification process when the Roamio boots up. If the drive imaging process of a stock drive doesn't work, is there a utility that can read the raw sector data on a drive, save it and then rewrite such to another drive? Again I'm not describing using one of these prepared drives to accomplish this but to use a initialized stock drive to prepare a 4tb drive. I have a extra basic Roamio and I'm pretty sure I going to buy a 4tb drive and start experimenting, in the worse case I can use the 4tb drive for other purposes if it doesn't work out but I'm hoping others might chime in and offer practical ideas. I'm willing to start something with providing the basic hardware and time, however I need assistance from some of you more knowledgeable TiVo hard drive gurus. What do you think?
