dion training file server uses a raid 5 for its main data store. recently, the raid began flashing from green to yellow. additionally, an alert was received that stated, raid array disk 1 failure. unfortunately, the company no longer has any spare 1 tb, 5400 rpm seagate drives, so a technician replaced disk 1 with a 1 tb, 7200 rpm western digital drive. when the technician attempts to rebuild the array, the drive stays in degraded operation and continues to alert that raid array disk 1 failure is occurring. what is the most likely cause of this issue?
