So I have an Asus A8V Deluxe mobo with the VIA VT8237 chipset and I recently bought this newer WD SATA drive: http://www.newegg.com/product/product.asp?item=N82E16822136075 After install, the drive is not recognized by mobo. There are many comments on newegg there and other places on the web, hell, WD's own site that say you have to use jumpers across 5/6 to get the drive to go down in speed and be recognized by dated boards like mine. Too bad this doesn't work for me! I tried it using both primary and secondary sata ports, new cables, and all jumper config pairs on both ports! WD support has nothing to offer except a new drive, which I would guess would behave the same. But if the jumper fix works for all, why not me!!
