Hi Everyone,
Back in January I upgraded my 500GB Tivo to a 4TB SuperTivo using the Seagate STDR4000100. It seemed to work fine at first but then I kept seeing lockups and freezes.. to fix this you would just have to reboot the tivo, but then 8 months later (about a couple of weeks ago), I tried rebooting it for 20 straight minutes, many times, and I would get the flashing lights on the front of the Tivo, basically advising that the Tivo couldn't find the drive/there was an issue with the drive.
Once that happened I popped in the original Tivo drive and the Tivo booted right up. I then had to call Comcast and have them update the cable card pairing, as each new Hard Drive is a new "device ID" and the pairing has to be fixed. So the fact that this original drive works tells me the Seagate wasn't happy... My wife continued to use this Tivo for a couple of days, recording some shows and so on.
After reviewing all the very informative posts, and discovering there is no apparent reliable 4TB 2.5" option out there (none seems to exist yet - just the Seagate I already tried...), I decided to try a sector-by-sector copy from the Seagate to a new 3.5" 4TB drive. I decided on the 3.5", 4TB WD RED. I chose this drive as it is rated for 24x7 use for NAS systems, so should be good for DVR use, and several folks have used them without issues. Following Ross Walker's guide to fixing a broken Tivo, I tried a sector-by-sector copy using a Linux boot drive (usb thumb drive) and ddrescue. After about 14 hours of waiting, the copy finished with 8277kb/18 errors.
I then connected the WD RED drive to my Tivo using the same components as outlined in this thread by mark1958 (nice work Mark!):
http://ift.tt/2dck9mg. Upon first bootup, the Tivo went to the splash screen, then rebooted again to the splash screen. The Tivo booted up but when I went to "My Recordings," there was nothing there. My recordings were gone. I tried the kickstart 57 trick but after the green recovery screen and several minutes later, Tivo booted up with no recordings.
So, my recordings are gone. I have no idea where they went.. did the original Seagate have corruption in the recording area of the drive table? I have no idea. Alas, the ddrescue trick didn't work for me, and all the recordings are lost.
I had to go on a business trip so I popped the original Tivo hard drive back in. Recall that my wife had been using the Tivo with the original hard drive for a few days before I had the chance to put the WD RED drive in, and had recorded some shows on it. Well, surprise.. same damn thing happened as when I booted up the WD RED: Went to Tivo boot screen, then rebooted again and 2nd time at Tivo boot screen it finally went to the Tivo main screen. I checked recordings... AND THEY WERE ALL GONE! What the heck? Did Tivo release some sort of firmware update, including a feature to wipe the hard drive every time a new one is connected? I have no idea what happened here. Very, very frustrating.
Went on a business trip and now that I'm back, need to plan a time to replace the original Tivo HD with the WD RED 4TB in the enclosure. I wanted to plan this work to occur while I'm in town, in case the tivo craps out...
In the old days you could disconnect a Tivo hard drive, do a sector-by-sector copy to another drive (and then have a backup), then pop the original back in the Tivo and continue using it. Now, it looks like that option is out the window. It seems if you disconnect a hard drive and connect another, Tivo formats it like a new drive. NOT cool.
Anyway, long story short, I plan to connect the WD RED 3.5" 4TB drive soon using an external enclosure, so that I have a 4TB Tivo again. At least the sector-by-sector copy preserved the data format and the Tivo sees all the free space (shows up as 639 HD recording hours). Hopefully this one is more reliable than the Segate 2.5" 4TB. I am really sad about losing the integrated design - loved having the 2.5" drive self-contained within the Tivo - but it's simply not worth the hassle and flakiness (not to mention eventual failure!).
Has anyone else had this experience, where the Tivo initializes the hard drive every time a new one is connected (even if it is a backup from another drive)? Is my Tivo possessed? Am I doing something wrong? Ugh!
