First you should post in the 98 newsgroups, NOT the XP ones as the procedure
is quite different.
With Windows98 you will have to use a Startup Diskette aka EBD, and create a
partition, then format the drive.
With XP you right click on My Computer, select Manage, then use the Disk
Management tab, and partition and format from within Windows.
Of course, the other way to setup a new drive is read the instructions that
come with each and every new hard drive!
