I started with a working 80 gig from a 540 and ended up with a clunking 80 gig, no working backups, and no copies. I'm trying to upgrade an 80 gig to 250 and keep the 80 as a backup in case of failure.

I used the mfsbackup|restore a couple of times, that made disk that went in the power/almost there loop. Then I partitioned and formatted a drive with Fat32, mfsbackup to that drive and mfsrestore to the new drive, several times. Finally, I used dd to make a copy, got an error. Used dd con=.. and got lots of block errors and some light drive clicking. This bothered me since it was a first and I stopped it(Ctrl-C or something). Put the old drive in TiVo and got GSOD or persistent thunking.

I've been very careful with the original drive since I could get a working backup. What happened with the mfsbackup/restore and how did dd kill the drive?

At this point what are my options to get a working TiVo? This is an out of town friends box that I would like to return by 12/26/06.
