TiVo just announced the implementation of eSATA and the officially supported TiVo Hard Drive available ONLY from Best Buy. So this begs the question. Are our OLD hard drives still going to work or will TiVo upload some software that will make any but their drive useless? I literally JUST installed TWO Hard Drives into MX-1 cases. Now I wonder if I ought to just return them... Has anyone heard anything from TiVo Inc. or TiVo Pony about using other drives other than the official TiVo drives?
