If I read all the archeives correctly, is it safe to say using a Maxtor 120GB DiamondMax 10 (may have been UltraMax 10) for an upgrade is hopeless? Before finding this forum, I tied using the said HDD. I had problems with choppy / blocky / stuttering video. I checked the cable seating, made sure it was a Master, did over 10 power cycles, still had no luck. I replaced the drive with the original Quantum 30GB, and all is well with the Tivo again. Can someone please confirm that the Maxtor drive is useless for my upgrade, or give me some things to try? Thanks.
