My younger brother's TiVo has started freezing. We tried unplugging the wireless adapter, so I don't think it was caused by an incompatibility between the wireless adapter and the latest TiVo software. We also read this thread which pointed toward this being a hard drive problem, although at least one person in that thread pointed out that a bad power supply can mimic a bad hard drive problem. So we're trying to isolate the issue and then replace anything that needs replacing. TiVo model: Series2 40-hour 24004A Age: ~2 years old Service: Lifetime Connection: Phone line for contacting TiVo, D-Link wireless adapter for sharing shows with the other TiVo in the house. Symptoms (as described by my brother): Is there any way to rule out the power supply so that he doesn't buy a hard drive and then find it doesn't solve the problem? Mark is considering buying an InstantCake CD from 9thtee and a replacement hard drive. Have others had good luck with InstantCake? Does anyone know of some good deals on hard drives that would work in this model TiVo? I guess I'm lucky in that none of my TiVos have ever had this issue. But that means I'm not much help to Mark. Hopefully some folks here can steer us in the right direction. Thanks everyone!
