My problem is that my 640GB Caviar Black is only being reported as 1.5g instead of being reported as 3g in my system (my motherboard only supports up to 3g). My Seagate 1.5TB drive gets recognized as 3g so I’m a bit baffled here. The dated compatibility chart lists my motherboard and chipset as being 3g compatible.
Here are my relevant system specs:
Motherboard: Asus A8N32 SLI Deluxe - latest beta Bios 1405 (01/08/2007)
Chipset: Nvidia Nforce4 - latest driver 15.23 (09/12/2008)
Hard Drive: WDC WD6402AAEX-00Z3A0 - Firmware 05.01D05
OS: Microsoft Windows 7 Professional 64-bit
Here are some pics of Microsoft’s speed test in the device manager of both of my hard drives on the same SATA controller. Note the Barracuda running at 3g.
I’m really quite stumped at this. I did have to update the firmware on the Barracuda in order for it to be properly recognized so maybe I need to do the same with the Caviar? I thought it might need to use a jumper setting but the documentation only showed that you only use it for 1.5g compatibility mode or for SSC - which I’m not using. Unless of course the documentation is wrong and I need to be using a jumper somewhere.
