hello I need some help with a hard drive I just put into my system is this is the wrong part of the forum please let me know

I recently installed Vista with on this machine with this new HD deatched though it had previously been used in this computer running xp.

It is a IDE hard drive and although device manager recognizes it as a disk drive I cannot get windows explorer or disk management to notice it. It has a ntfs format.

Thanks please let me know any additional info I should post. my other drive is SATA drive
