SCSI PCI Card Problem

I’m a newbie, and I’m not sure if I’m posting this in the right forum. (Moderator: If this question is in the wrong forum, then please move it to the appropriate forum.)

Anyway, here is my problem: I recently installed a SCSI PCI card (Adaptec AHA-2940UW) and it didn’t come with driver software because I bought it used from eBay. I went to the Adaptec website, and they don’t have any driver for Windows XP because they claim that Windows XP already contains the driver for this card.

So I installed the card in a PCI slot and then I re-booted, but the “Hardware Wizard” didn’t come up, and when I went to “Device Manager”, it didn’t say anything about a SCSI card. Then I tried opening the “Add New Hardware” control panel and I put my Windows XP installation CD in the CD drive (because it should contain the driver), and I let it scan for new hardware, but it said that no new hardware was installed, so it didn’t look for driver software.

Then I ran three programs which show the details of my computer hardware, but none of them said that there is a SCSI PCI card in my computer. The programs I ran were Astra32, Test My Hardware, and Dr. Hardware Sysinfo.

I haven’t yet tried connecting my SCSI hard drive to the PCI card, but I doubt that it would make any difference if the PC thinks that the card doesn’t exist.

Is the card defective? Should I send it back to the seller and ask for a refund?

(The reason why I bought this SCSI PCI card is to connect the hard drive from my old Macintosh Color Classic computer (which is in SCSI-1 format) to my PC in order to transfer files from my Mac to my PC.)
