I have had the same HDD in my HD Tovo since launch, mid 2008 i think. I took the original disk out the day i bought it and installed a 1TD disk which is still going strong.
I think it would be a good idea to replace this disk whilst it is still operational. Whats the biggest IDE HDD i can purchase and what software do i need to clone the existing disk.
I still have the original 160 unused disk in my top draw.
