Advertisements I have a Hughs series 1 directv tivo GXCEBOTD unit. The unit had been upgraded from a single 40 gb hd to a two 40 gb hd unit several years ago using msftools. The unit recently stopped working and constantly reboots in the welcome powering up screen. Thought I might have a failing haed drive problem. Purchased a copy of instant cake and formatted a new 160 gb western digital hard drive. The same thing occurs with this drive too. Does anybody know what the problem is? Can it be fixed? Thanks to anybody who can respond to this cry for help.
