I am replacing the original 500gb hard drive in my TiVo Premiere Series 4 with a new WD 1TB hard drive. I was originally told that all I had to do was install the new hard drive into the TiVo and it would automatically format the hard drive to work in the TiVo. However, while this is true for the Roamio model, it is not true for the Premiere model. When I installed the new hard drive and powered it up, all it did was continuously flash all the LED lights. The only instructions I have found in this forum regarding formating new hard drives to work in TiVo involved complicated steps to transfer all the recordings from the old drive to the new drive. I am not interested in transferring recordings to the new drive. All I want to do is format the new drive to work in the TiVo. Can somebody tell me how to do this? Again, let me state that I am not interested in transferring the recordings from the old hard drive to the new one. Just tell me how to start fresh with this new hard drive and format it to work in the TiVo. Thanks for any assistance.
