I have a DTivo (Samsung 4080R) and the drive finally gave out so yesterday I replaced it with a replacement drive from Weaknees. Actually I've had this drive for about a year thinking at the time the DTivo drive was going out but it turned out not to be so. Anyway I installed it and I'm at 6.2xxx so I tested the phone connection and forced several calls to the servor and did notice it did download some data. My guide has also fully populated. This morning I noticed there was "Service Data Download" at 2:30am but not sure what that was about. So will I eventually get the 6.4a update and if so can I do anything to speed it up, or will I be stuck at 6.2xxx? I really miss the deleted items folder so evidently I did have 6.4a on my old drive.
