wd5000azdx won't boot tivo

I am trying to instll a wd5000azdx into my tivo.  I can copy the operating system to the drive with my windows computer but it won’t boot.  I wonder if it is an issue with the 4k sector size.  Is there a way to fix this so the tivo can see the drive.  I have also been recommended to try wdidle but I am having trouble getting a boot disk to run it.

You can try running WD Align

You can download the advanced format software from the link below. Also check if your hard drive model is compatible with tivo.
