Assuming you use Windows, you don't need special software for that, only Windows drivers for the SCSI card. When Windows recognises the SCSI card you can partition and format drives the same way you would any plain IDE drives.
However, if you use Windows 98 or earlier, you'll need to install DOS drivers and use the Adaptec DOS partition utility, unless you partition the drive with a third-party application such as Partition Magic.
