Advertisements HDR 114, upgraded to dual DiamondMax 10 160 GB PATA133 HDD. That lasted about 6 months, then TIVO died, could not get past (TIVO is starting up) screen. Removed those because of heat/PS issues described to me by members of this forum. Changed to a single 6L300R0 QuickView drive as recomended by those on this site. Well, that was April, now it's October and yet again, TIVO is stuck at the startup screen, the past week inconsistant recordings and not being able to playback shows I recently watched. I tested all drives with MaxBlast, and they all pass the tests. The 160's are actually used in some of my PC's now without issues. So, the drives are not dying, they just won't work after about 6 months... I have a cachecard in the TIVO, that is the only other MOD I have made. I just went back to my original drive that came with the unit, only 14 hours or recording available, YUCK! What am I doing wrong here?
