1.) This forum is reserved for posting issues related to the Cnet forums themselves. For other issues, you should consult the forum listing and choose the most appropriate forum. In your case I would suggest the Windows Vista forum.

2.) You likely just need to enter your system BIOS and change look for a SATA/PATA/RAID compatibility setting. The exact name/location varies.

3.) A hard drive cannot be 'seen' by the operating system until it is formatted, something you can do under Windows Vista using Disk Management.
