I recently purchased one of the new Granite Digital Aluminum SATA Hot Swap Enclosures. I put the disk in the case, and connected it to a Firmtek 4 port PCI-X SATA controller. I connected it using the cable included with the firmtek adapter, and it recognizes the disk fine but it will not format it. I get either a input/output error or resources busy error notice. I've tried restarting the computer and using a different external port on the card. Does anyone have an idea how to fix this problem. Thanks.
