But it is only controlled as SATA150. A few things (I'm not doubting your claim of a problem, just trying to track it down): 1) What FreeBSD version and build date? uname -a would suffice. 2) What controller (atapciX) is mapped to ata0? You didn't include this in your dmesg output. 3) Output of atacontrol cap ad0? 4) Is your motherboard set to use AHCI for the SATA (ICH7) controller? There's reports that SATA300 is only available/used on some controllers when AHCI is used. 5) This drive isn't available in the United States, so I'll have to go off of foreign docs. AUS docs don't show this drive as having any such jumper, but the docs are sparse: http://www.samsung.com/au/support/productsupport/download/Model_Select.aspx?type=Hard+Disk+Drive&typecode=12&subtype=HDD%283%2E5%29&cmssubtypecode=1203&model=HD080HJ&filetype=UM 6) Have you tried following the opposite the documentation you have recommends? That is: try putting the jumper on and see if SATA300 is negotiated? Or is it SATA150 regardless of the jumper setting? 7) Another FreeBSD user using this drive does in fact see SATA300 negotiated speed from it when using an nForce MCP55 SATA300 controller. http://unix.derkeiler.com/Mailing-Lists/FreeBSD/questions/2006-12/msg01421.html I'm left wondering if there's actually two revisions of this drive floating around on the market; an older one that only supports SATA150, and a newer that supports SATA300. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
