Re: Why isn't my slave HD showing up?
That wouldn't make a difference really... definetly doesn't matter how old the drives are.
Try disconnecting the one that doesn't work and putting it as the Master, and maybe disconnecting the new one compltly to test to see if it reads it and boots. If this works then its defintly the formatting of the drives
