I'm new to Mac and loving it so far. I've been using Windows Vista Ultimate 64 bit for graphic and web design the past several years until I just couldn't take it any longer. Trouble is I had all my client files on an external Seagate hard drive with only an eSATA connection on the device (which I connected to my PC with the included eSATA PCI card. But apparently my new Mac Pro will only accept PCI-express cards, and I'm having a hard time finding a PCI-express eSATA card that supports a 64 bit OS (I'm using Snow Leopard). Can anybody point me to such a card?? Thanks!
