I agree with Jim Brady... I have used the services of Weaknees.com as well buying pre-formatted drives -- very easy to replace harddrive into a TiVo unit. Might pay a few extra bucks buying something preformatted, but I prefer that over collecting all the software you need to do it yourself online. Swapped out drives in both my Series 1 and Series 2 was very easy. Kept the original drives as backups in a drawer should the upgraded drive fail sometime off in the future.
