Take a look at this thread. There is a suspected bug in the builder software. It might be necessary to rebuild the drives using the builder image again in order to set up the partitions. This should be for the new drive that you are adding only. Hopefully, you did not rebuild your original drive - not that it would hurt it, butyou would lose the data (music) that was on it.

I would add, though, that it looks like you are seeing physical errors. Please double check your cabling, your jumper (slave drive) and your IDE header.
