I've read that you need to image the old drive using winmfs but can't find it anywhere.
Can someone help me?
I'll begin the help by pointing out that the software (like WinMFS or the MFS Live cd or MFS Tools on which it was based) that worked on Series 1, 2, and 3 hard drives does not work on newer ones than that, and as you note, you have an S4.
You need to start here
to learn about the software needed, to find out from where you can download it, and you can post a request in that thread for an image for your TiVo.
If you're going to use a bigger drive than the one that your TiVo came with, you'll also need jmfs to expand into the extra space after restoring with DvrBARS, and you learn about it here
(and if you want a TiVo that takes a blank drive and does all the work for you, you need a Series 5, 'cause that only started with them)
