Bought a new SATA III hard drive, want to use it on a Sata II port

I just bought a WD Green WD40EZRX 4TB hard drive.

I have a Gigabyte Z77 D3H motherboard.

i want to plug in my new SATA III 6.0gb/s drive into a SATA II port. Will this work or will it bottleneck my new drive down to SATA II speeds? It's not a SSD, just a regular HDD.

Also, what's the best/easiest way to clone my old 2T hard drive into my new 4TB hard drive? It's a Western Digital, my old Seagate came with software that does this. Do I have to use a DOS program to clone?

    SATA II, SATA III....makes no difference to an HDD. You'll see no performance difference, as a typical HDD can't saturate a SATA II interface.

    But why are you looking to clone to the new drive? Just add it as a second drive.
    There are multiple tools that can do it easily, but if your current drive is OK, I wouldn't.
  2. I'd rather clone the drive, format the old one and use it as a back up. I'm pretty sure the newer drive is faster, too.
  3. Western Digital has Acronis program on there to clone the drive, but it seems like it will be doing this through Windows. The last clone program I used, I had to make a boot disk and do the clone process through DOS. Does anyone have any experience with Acronis? Like if I clone it, then take off the hold hard drive, then make the new hard drive my master, will it be able to boot from it exactly like the old drive?

    CloneZilla, Macrimum Reflect, Acronis Trueimage, DriveimageXML....all can do that.
  5. I'm gonna try Acronis since it's available from the Western digital support site. You don't have to log out of Windows to clone the drive you're using. I hope it works, not sure how it's gonna clone the MBR. I think you can't access it through Windows.
