Esata problems

i just recently installed and media bay drive and it includes esata. I plugged in my external hard drive and windows is not recoinzing it. I have tryed to connect it internally and windows read the drive but when i use the esata port it read it does any no if Vista has any problems with esata drivers or should i get a different esata 2 sata cable?

How is this media bay drive connected to the motherboard? Does it require a driver to be installed?

no its only required if its 98 but there is none. Everythign else on the media drive works except the esata connection i dont noeif its the connection or its the cable i have sent out 4 a new cable to see if thats the problem.
