A few years ago i upgraded my Hughes SD-DVR80 from an 80GB drive to a 500GB drive using MFSLive with no issues. A few weeks ago i started seeing pixelization and audio issues along with random reboots so i figured it was time for a new drive. As my system uses PATA i dug around and found that most series 2 systems will work with a SATA drive with an adapter. So i figured i would go with a new 1TB SATA drive but i found because i already expanded my drive once that MFSLive will not expand it again. However i found that WinMFS had expansion of already expanded drives built in so i decided to upgrade again. With the background info covered here's what i have tried and where i am now. I bought a 1TB WD WD10EARX from BestBuy and an SATA to IDE adapter from amazon (if needed i can post the url later as i don't have enough posts for links) I used WinMFS MfsCopy to copy and expand my 500GB drive and when putting the drive in the Tivo it froze at the welcome screen. This lead me to the possibility that i had issues with WD intellapark so i disabled it with wdidle3 but after it was disabled the Tivo got stuck in a reboot loop at the welcome screen. Next i tried just restoring the drive with no media to see if the copy went bad but that too ended up in a reboot loop at the welcome screen. So i put the 500GB drive back in and everything works. So i figured it must be either the drive or the SATA to IDE adapter. So i bought the Weaknees SATA to IDE adapter (and even their IDE cable...) that is supposed to work with my SD-DVR80 however the adapter and the WD hard drive gave me the same results, welcome screen reboot loop. So given that not all drives work adapters and Tivos' i figured i would test a Seagate drive so i tried the copy again with a 1TB Seagate ST1000DM003 drive and have the same results. So in summery i have tried two drives with two different SATA to IDE adapters with both a full copy of my 500GB drive and just a OS/kernel no media copy and each drive with each adapter and cables in all possible configurations each configuration changes the time the loop takes to reboot some very fast (mainly with longer or older cables) some take up to 10 mins. Also the disk copies where done on an intel chipset motherboard with PATA using the SATA to IDE adapters. At this point i'm out of ideas with the hardware i have and it turns out that the random reboots may have been from a bug that DirectTv has informed me about and is refunding me 10.00 for the issue.... To clarify the reboot loop is just on the welcome screen it never gets to "almost there..." and the front panel led never changes to orange which as far as i know that means its not getting to the point where it loads the kernel. Any help or ides on how to get out of the reboot loop would be appreciated.
