Question: My hard drive is 160 GB, when I install Windows 2000 or Windows XP, I can only see 137 GB. However, when I install this 160 GB hard drive on the ATA 133 RAID card, I can use whole 160 GB. What's wrong?(5/15/2004) Answer: If you would like to use whole 160 GB as only one partition while installing the Windows OS, please make sure that your OS is Windows 2000 service pack 4 included or Windows XP service pack 1 included.
When you install the hard drive on the RAID card, you would need to press F6 to install third party driver during the Windows installation, and the driver is the reason why you can use whole 160 GB even your Windows XP service pack 1 is not included.
