Consider the following scenario:

• You are using a Windows Vista-based computer.
• The computer has a Serial Advanced Technology Attachment (SATA) hard disk drive that has full-disk encryption capability.

In this scenario, when the SATA hard disk drive is operating in Parallel Advanced Technology Attachment (PATA) mode, the hard disk drive may stop responding. Additionally, the computer may crash.

Parallel Advanced Technology Attachment: A standard interface for connecting storage devices such as hard disks and CD-ROM drives inside personal computers.

Consider the following scenario:

• You are running a Windows Vista-based computer.
• The computer has a Serial Advanced Technology Attachment (SATA) hard disk drive that has full disk encryption capability.

However, when the SATA hard disk drive uses Parallel Advanced Technology Attachment (PATA) mode, the hard disk drive may stop responding. In this situation, the computer may crash.

After you install Windows Vista on a computer that uses an SiI Parallel Advanced Technology Attachment (PATA) chip from Silicon Image, the computer does not recognize an attached optical drive as a drive that supports recording. Therefore, you cannot use the computer to burn CDs or DVDs.
