Hi RGB76 - I recently set up two new HDDs in Windows XP Pro - if you right click the My Computer icon, and then left click Manage....it will bring up the Computer Management applet.
In there, all I did was to selecr the new HDD and Windows just came up and said that it needed to initialise the dsik before formatting etc... could take place. Did this, and all was well.
Want to try the above? - waht OS are you using?
