Found this article http://support.microsoft.com/default.aspx?scid=kb;en-us;224526 The way that I got round it was to stick a drive into another NT4 machine format the drive, then put it back and then install.

I need to know if there is some way that I can slipstream in an SP4 cd into an NT4 Server installation CD. Here's why: (and if you can help me out here too, bonus points) I have to rebuild a generic black box server with NT4 on it to support Siebel. I finally got 2 20G Western Digital drives installed in it, and they are recognized. But when I try to install NT4, they come up as 7.8G drives. A KB article I found says that SP4 has an updated Atapi.sys that will allow formatting of large hard drives. And I *reallllly* need these larger drives. So if anyone can help me out, you'll get a virtual beer. Thanks much, Jennifer Jennifer Hooper Peregrine Systems, Inc. Sr. Network Engineer mailto:jennifer.hooper@xxxxxxxxxxxxx
