The_Prophecy :
I am going to stick with wusy on this one..... google it. The one bit of info I will give you though, is that the cables and connectors for both SATA1 and SATA2 drives are the same. As for making the SATA2 drive work on the older interface, i'll let you figure that out for yourself.
I googled it though my query was "sata 3 backwards compatible?" and this thread is what came up.
I've long wondered why people take the time to respond with queries with "Google it" unless that is simply an addendum to their "better" response, and given for the sake of those who haven't yet learned that googling frequently gets far better and more thorough responses than asking a small group of people that might be looking at a thread.
If I sound like "Google it" hits me the wrong way, that's because it does. I always google every question I have and it's quite annoying to take the time to follow a response, only to find the answer is "Google it."
Don't want to piss off the moderator, but even moderators sometimes come off with less than sterling responses.
