I followed the Hinsdale instructions to add a 250 GB drive to my 80 GB Tivo. What I didn't realize until it was too late was that the Hinsdale software only supports the 137 GB limit. Can anyone point me in the right direction to get the full use of the 250 GB? Unfortunately I was an idiot and did not make a backup prior to adding the new drive. I have not recorded anything new since installing the drive. I have tried to issue the mfsadd command with the weakness CD with no success.
