You don't indicate whether the hard drive is the primary drive or a secondary drive but either way, after a disk is wiped (not "whipped" as you put in your post.), the disk needs to be partitioned and the partition/s need to be formatted to properly show how much space is available . If it's the primary drive, then put the operating system installer disc into the DVD/CD drive and let it partition and format the drive. If it's a secondary drive, then access Windows on the primary drive, then "Disk Management" and partition and format from there. The link below should help you get that done.

Hope this helps.
