Samsung SIR-S4120 ... replacement drive/unit stalls out at logo screen
I purchased a replacement hard drive for a Samsung SIR-S4120 DirecTV/Tivo unit.
I'm fairly certain I did everything correctly during installation (Lou's directions are perfectly clear).
But when I powered the unit up it stalled out at the logo screen (the one right after "Powering up ...") and went nowhere. The same thing happens every time I shut the unit down and restart it; the unit goes to the logo screen and then gets nowhere.
The hard drive is able to spin up -- I've heard it.
What are my next options -- short of getting a non-Tivo DVR from DirecTV?
Is there some way to re-set the unit and try again?
Can I test the replacement drive by connecting it to my home computer?
Is there anything I can try?
Thanks for the help.
