Formatting
The DX4500/DX4600 automatically detects when a new drive is installed or when a current drive is switched to a different SATA connector. After the DX4500/DX4600 starts, the system prompts you to format the newly installed drive. Drives that have not been switched to a different SATA connector are not reformatted.
WARNING: Before initiating a format procedure, verify that the drives are reinstalled in the same position and reconnected to their orginal SATA connectors. For information, refer to Before You Begin on page 6 and the DX4500/DX4600 server operation/programming manual (C2674M).
