B. Use GPT, which does not have the CHS baggage. It is easier and more bsd labels doesn't have too versatile. My systems with GPT disks don't complain about track alignment. Or maybe that's ahci(4)'s doing. ___ freebsd-hackers@freebsd.org mail

2) Although I don't know a lot about boards, it is my understanding that ASUS makes pretty good ones, and they have always worked for me (and the firmware is typically quite good). maybe it's strange for for a long time i NEVER really succeeded making stable configuration from popular parts.

people are often trying to squeeze out that last drop of performance, Linux is certainly a steaming pile of crap. BSD is orders of magnitude better, but hey, that doesn't take much. just pray FreeBSD will not incorporate too much "modern technologies" if you know what i mean. But don't br

Apparently, I owe everyone an apology. I found out (a bit too late) that the WD 1 TB "black" drive that had come to me in sealed anti-static bag with a warning on it about "Advanced Format" drives (and possible OS incompatability) was not in fact itself an AF drive. Rather it is a traditional d

Hi, Yes. atacam supports NCQ. The older IDE/ATA code doesn't support NCQ. The CAM ATA code (ie, atacam) supports it if the drive supports it. So, the "FreeBSD doesn't do NCQ" point is incorrect. If you don't believe me - look in sys/cam/ata/ata_da.c, look for ata_ncq_cmd(). Adrian ___
