Addonics Cardbus to expresscard

[tmnt]

I can't get this card to work on my dell xps 1710 with my eSata external hard drive. The hard drive is recognized with usb but not eSata. My eSata pcmcia card is installed but the drive, a Seagate 750gb sata, comes up with a yellow question mark saying 'no driver installed', what
the?

EDIT: here's the card I have. http://cgi.ebay.com.au/Laptop-PCMCI...oryZ3710QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

Any ideas?
