Can use the drive in either NTFS or you can format in with the Apple's utility. The choice to reformat is up to you to decide. I didn't reformat it.

I am putting my HP laptop's hard drive (320gb) into an enclosure (http://www.vantecusa.com/gl/product/view_detail/214). I want to use it as an external hard drive on my Macbook Pro 13".
Do you have to reformat the drive on the Mac? If so, how? I appreciate any help and/or if you know links where others explain thoroughly how to do it, whether its through video, images, or text.
Thanks
