Drive to Drive, or similar app, still available?

[macx]

Several years ago (maybe more than several) I had that little app that worked
so well when copying my C drive to a different hard drive while it was running, including Windows.

I just did a Search and can't find it.

Anything like that available?

I may need to put in a new hard drive for my C drive shortly -
I've got a drive making noise and I don't want to take a chance
on losing all the installs and setups on my apps and have to do
it all over again. I've already lost one of the 3 drives I put in
at the same time when I built this desktop several years ago.

Thanks!
