It is important to note that different SATA host adapters handle the power sequence in different way. Some support all five power sequence modes, the other can only support Hot Boot.
Before disconnecting the SATA drive cable from the computer, we recommend you to shut down the computer first, because current system driver and SATA host specification do not make SATA hard drive 100% removable like USB or Firewire hard drive.
FireWire and USB Connection for MacOS 9.2 and MacOS X
When the Enclosure is connected to the computer, MacOS X will recognize it automatically, initialize it (if the drive is not initialized) and mount the drive to desktop. All five power sequence modes are supported in Firewire or USB connection.
Note: MacOS X provides a Disk Utility to create multiple volumes, which is located in Utilities folder inside Applications folder.
