A family member unhooked my hardrive and hooked up another to apparently check theirs out then reconnected mine. Every time I start the computer now I get the Found New Hardware message for the CDR drive and the DVD drive. Their respective icons appear in the Devices with Removable Storage in My Computer for a brief moment then disappear and neither unit will spool up when a disc is installed. Any ideas will be greatly appreciated on how to get the drives to be recognized by the computer and functional again.
