Looked at dmesg, but am unsure of how Freebsd would
identify a SATA drive.

it says it's sata like that:

ad10: 305244MB <SAMSUNG HD321KJ CP100-10> at ata5-master SATA300
ad12: 305245MB <SAMSUNG HD321KJ CP100-10> at ata6-master SATA300
ad14: 305245MB <SAMSUNG HD321KJ CP100-10> at ata7-master SATA300
ad18: 476940MB <SAMSUNG HD501LJ CR100-12> at ata9-master SATA300
ad20: 476940MB <SAMSUNG HD501LJ CR100-12> at ata10-master SATA300



Wouldn't Freebsd fail to install if it didn't recognize the drives
as SATA ?

no. but if it recognizes it as ATA-33 or like this - something is wrong.

Exactly my problem. It says
ad4: DMA limited to UDMA33, device found non-ATA66 cable
ad4: 152587MB <SAMSUNG HE160HJ JF800-24> at ata2-master UDMA33
ad6: DMA limited to UDMA33, device found non-ATA66 cable
ad6: 152587MB <SAMSUNG HE160HJ JF800-24> at ata3-master UDMA33

Weird. What would cause this ??


That is usually what happens when the disk controller is one that FreeBSD
does not have support for, so it treats the controller as a "Generic" ATA
controller. Should normally work fine albeit with somewhat suboptimal
performance. (And even though it says UDMA33 a SATA controller should still
work at SATA150 speed, so the performance penalty should not be so severe.)
