Randy, There are exactly two steps for dealing with an ide drive with bad sectors: 1. Move the data to a new drive immediately if not sooner. 2. Discard/RMA the old drive. Bad sectors on an IDE drive is a bad thing. Most IDE drives automatically hide bad sectors by redirecting bad blocks. If writing to an IDE drive fails due to "bad sectors" that means the drive has already redirected enough data to fill the redirection area. If you're seeing bad sectors, chances are the drive has gained a lot of new bad spots and as a result is on it's final legs and shouldn't be trusted, EVEN IF you can reformat the drive. - Forrest W.
