I have a Digital Audio G4 with an IBM Deskstar hard drive. I am installing a 2nd Western Digital IDE hard drive. The computer is recognizing the 2nd drive, but now my USB accessories have stopped working. I have searched for a solution, but don't see anyone else having this issue. I have Mac 10.4 and I have a Quicksilver processor in my Digital Audio. Any ideas would be greatly helpful! Thanks!
