Yes, but it depends on the computer's operating system (Mac OS or Windows). Sonnet Tempo SATA PCIe, PCI-X, PCI, and ExpressCard/34 cards support drive hot swapping only when used in Mac computers running Mac OS. SATA drive hot swapping is not supported in a desktop or server PC running Windows XP, Server 2003, or Vista. A SATA drive appears to Windows as a fixed hard drive and there is no mechanism in Windows to prepare the drive for removal except in notebook computers.
Tempo SATA and SATA Pro ExpressCard/34 cards support drive hot swapping in both Mac and Windows notebook computers.
Failure to power off a Tempo card before ejecting it may have an unpredictable result for OS X.
You should follow these steps:
1. Unmount any drives attached to the Tempo card by dragging them to the Eject icon in the dock.
2. Click the Card's icon in the menu bar and select "Power Off Card" from the drop down menu.
3. Push and release the Tempo card to eject.
