-- Drive with bad blocks copied to new drive? (http://archive.tivocommunity.com/tivo-vb/showthread.php?threadid=25445)

You might be a little quick to jump to conclusions about your 14 hour drive. Just because the errors are reproducable doesn't mean they are even your TiVo's fault.

For instance, a few weeks ago, my roommates' recordings of Buffy were messed up - big MPEG artifacts, times where the audio (and sometimes video) would completely cut out. They were questioning whether the TiVo was having problems, but a quick look at the live feed using the TV's tuner revealed the problem was upstream somewhere, and the TiVo was just recording what was there.

If you do have bad spots on your drives, if you listen to your TiVo while playing back one of the reproducable errors, you should hear the drive go KA-Chunk when it retries the read.
