Advertisements I tried running the mfsadd again with the new "-r 4" switch and it didn't fix the problem. I then did a restore to a blank 300gb drive and Tivo booted up fine. Tried restore to original drive which restored fine but got a message expanding the swap failed. Tried the mfsadd again with original 250 gb drive (A) and 300 gb (B) using all the command switches advised. The results said that I had increased my hours the appropiate amount but when when I put everything back in the tivo and booted up the system info screen still only shows the 30hours HD 300hours SD?!? I've been at this for several days and I'm close to giving up. Not to mention that the weakness bracket I bough includes this fan that makes the tivo hum and vibrate at a level that I don't think I can live with. A single 500gb drive upgrade is probably a smarter choice. The double drive setup has not gone as smoothly as advertised. Anyone...anyone...Buhler? Why is the mfsadd not working?
