Is it a PowerEdge server? Some sort of embedded RAID controller (PowerEdge and Precision workstations both have those)? More information required to fully answer. A Dimension desktop shouldn't have this issue, but a PowerEdge or Precision with PERC or CERC set up will have this issue, and you need to access the controller's setup to tell it the other disk is gone.
