Actually, I spoke to IT Support here at work, we used one of their new computers with internal sata drives and the samsung software we used said it has successfully knocked it down to 1.5Gbps so I'm hoping this is it
. I can't wait now to get home and try it out. In defence of samsung, despite my criticisms, the drives are now supposed to be able to negotiate the interface speed on the fly, so it could just be down to shortcomings in the negotiating capabilities of the controllers I have (guess I wo'nt be sending them into any hostage situations just yet), but it does seem silly that in order to "force" it to be backward compatible I need a sata II controller to do it. Will let you all know how it goes tonight. In fact sod it I might nip home at lunchtime!!
