[QUOTE="flash, post: 113441, member: 885"] Lightroom uses a few things to determine whether an image is a duplicate and it always errs on the side of caution. (say for if you have two camera bodies - eventually you'll get two different files with the same name) It looks at the file name and time of creation data mainly (but also sees the camera serial number and pixel size). Hence it's not a 100% effective. After you have you new catalogue and images on your new drive you can then select all images in the catalogue and sort by capture time. Then it's simply a matter of scrolling through and marking any extra duplicates by hitting the "x" key. They'll then be greyed out. When you're done you can then filter for the rejects (that's what the x key does - mark an image as a reject) and delete them all in one go. If you've done the copy from an old location to a new one like I sugested, you can delete them from the disc. If you're paranoid you can keep them and just remove them from the catalogue.
