...if you have a cron job setup and your Tivo crashes, the cron won't run. I've now gone to the extent of having it connected via a Dick Smith Timer switch which literally cuts power for 10 mins everyday at 3pm (Bold and the Beautiful is on I think so thats safe enough to avoid) just to ensure it isnt frozen when I get home from work.

It ran for about 3 days non-stop up to yesterday, then crashed 3 times. This is my second image on a second disk. I am going to try with another image and will also try the network card suggestion below. I never use Tivoweb now and have no other 'hacks' running.

A friend of mine tried 5 seperate images on 3 disks before getting one that is pretty much stable now so maybe its the luck of the draw.
