Whats wrong if two hard drives will not function even after verifying jumper settings?
There may be a compatibility problem between the two drives. Here is a step to verify this assumption: Test the new drive by itself. If both drives work by themselves then it is best to conclude that there is a compatibility problem. If this is found to be the case, try “swapping” (switching) the drive’s roles. In this case, what was the master will change to be the slave and the slave will change to be the master.
