Yes, we ran into this yesterday on a fresh install using the 7.1 beta 
CD as it was set to PATA mode by accident.  Also, on some earlier 
BIOS revs, we had to turn off "enable USB legacy mode" as well as 
"EHCI handoff".  By default we set those to disabled as it seems to 
sometimes create a high interrupt load on the USB bus if its enabled.

If you forget to set the mode to SATA, the dmesg will look like

Sep 30 13:37:08 dev2 kernel: ad4: DMA limited to UDMA33, device found 
non-ATA66 cable
Sep 30 13:37:08 dev2 kernel: ad4: 152627MB <Seagate ST3160815AS 
3.AAD> at ata2-master UDMA33

and you will indeed get corruption

Turning onto normal SATA mode in the BIOS, you should see

Sep 30 16:14:15 dev2 kernel: ad4: 152627MB <Seagate ST3160815AS 
3.AAD> at ata2-master SATA150

... And everything works great.
