With one burst per command, that means one Crc per command, yes? Doesn't the Crc then grow weaker as the sectors/command increases? Anybody got an idea how much weaker how fast? (((I hadn't before now heard that lots of hosts choke over a Crc per block. I had been told that an Atapi Pio INTRQ per block offers increased immunity to ground bounce, crosstalk, etc.: the extra handshakes make a system observably more robust when you're assaulting it with electrostatic charges.)))

True statement for all modern HDDs. Fujitsus first generation UDMA chip terminated after each sector, and this did break some controllers (who didn't read the spec). If there were still drives doing this, we would likely hear about it. ... Subscribe/Unsubscribe instructions can be found at www.t13.org.
