Advertisements Has anyone tried replacing the drive inside a WD MyDVR expander? Mine is acting flaky and is out of warranty. I was thinking about dropping a 500mb Hitachi cinemastar drive in, rather than scrapping the whole unit. I'm curious if what the TiVo sees is the drive itself or the controller it's sitting in. If it's the controller, I wonder if TiVo would even know the drive had been swapped. Thoughts?
