I do not understand why I had such difficulty understanding your question. Sorry about that. It seems what you would like to do is to delete the partitions on the drive, create new partitions, and then format the drive. There are a few different tools to help with this.
1) Disk Manager in Windows XP - right-click My Computer, select Manage, select Storage/Disk Management
2) Hard Drive manufacturer's diagnostic utility (disk preparation utility)
3) fdisk, cfdisk
4) Partition Magic
5) Acronis Partition Manager
6) Most any linux installation CD. Mandrake provides QTParted very nicely.
7) FreeBSD sysinstall installation routine
Just be careful you do not accidentally delete the partitions on any good hard drives that are attached to the system. This is extremely easy to do with low level tools such as fdisk and cfdisk.
Wiping a drive clean is a different process and involves writing useless information to the drive, which helps to overwrite active viruses or confidential data. The hard drive manufacturer's diagnostic utility usually provides this tool, or you can use

I hope this helps to answer your question.
