    TiVo's approach to whole home was cool...copy programs from the DVR where recorded, to the DVR where viewed. This allowed you to move content that was "precious" to an additional DVR. I moved a lot of recordings around before I finally decommissioned most of my DirecTiVos. :)

    So, if you know, why can't we do it now?

    The old DirecTV Tivos had technology essentially 10 years old, were MPEG2 only (no MPEG4) and security/file security was highly different than today. When D* moved to MPEG4 the tighter security came into play.

    But regardless, back to the original question I asked yesterday, does anyone know of an external raid unit that can plug into the D* DVRs and will use its own os/firmware to translate the calls so that more than 2TB can be used?

    You could use 3 or 4 TB drive for the test - no RAID is need. A couple months ago we had hot discussion about the limit and it came to same ending - no, the limit is the same: 2 TB.

    About using RAID - yes, you could. Again the info 'what&how-to' already posted here.

    Regardless of what you hook up you'll be limited to 2TB. It's a partition limitation in the OS based on the format that the DirecTV receivers use.

    You could hook up a 4TB array but your post-format capacity would still be 2TB.

    There is no such magic.

    If there is a volume size limit in the underlying DVR operating system, no amount of outboard hardware or software can change it. You cannot install "hooks" into the DVR BIOS as the old Pee Cee devices did.

    This is what is known as a "business decision". It doesn't get any simpler than that.

    TiVo is generally not a company that was directly beholden to the programming providers but DIRECTV is so the DIRECTV TiVo-based products have some limitations that the standalone products do not. There have been hints to this in discussions that have been posted on DBSTalk previously. Most come from CES interviews.

    The discussion several months ago was about a single hard drive solution that could be used - ie - a 3TB drive.

    Just as Windows 9x could not read NTFS file structure, it a NT machine had the NTFS Drive on a share, the Windows 9x could read the files with the NT machine doing the translation.

    Just as the old Windows 16 bit systems could connect to Novell Networks with a server running a larger drive than Win 16 could handle.

    Just as there is IPv4<>IPv6 translation.

    There seems there should be an External Raid Device that would would take the D* calls and allow it to be processed to a larger storage than 2TB, just as there are units that allow this to be done for Windows 32 machines.

    Perhaps the key point was missed - implementing GPT - check that discussion's aspect.

    Again...

    All of those solutions were supported by adding device drivers into an open operating system (in most of your examples, drivers in the network layer). The DirecTV DVRs are not an open system...you can't add device drivers to them. They don't support any concept of shared disks (a requirement for the examples you note). Bottom line, 2TB is the limit unless DirecTV chooses to change it.

    The absolute best you can do, due to the MBR partitioning scheme limitaton of 2TB is to use a RAID array of 3x 750GB HDD's in Raid 0 (or 4x750GB drives in RAID 5 as I am doing) giving you 2,095.4 Gigabytes. You lose a little less than 50Gbyte due to the partitioning Limitation. Note that a 2TB drive is really only 1.86TB in reality so you are actually ~160GB short of 2TB using a 2TB drive

    This is what I am doing with the HR34... thus far with success see this thread for info: http://www.dbstalk.com/showthread.php?p=2996713#post2996713
