This section applies only to computers that have a CD-R, CD-RW, DVD+RW, DVD+R, or DVD/CD-RW combo drive. NOTE: The types of CD or DVD drives offered by Dell may vary by country. The following instructions show how to make an exact copy of a CD or DVD. You can also use Sonic RecordNow for other purposes, including creating CDs from audio files on your computer and creating MP3 CDs. For instructions, see the Sonic RecordNow documentation that came with your computer. Open Sonic RecordNow, click the question mark icon in the upper-right corner of the window, and then click RecordNow Help or RecordNow Tutorial. How to Copy a CD or DVD NOTE: If you have a DVD/CD-RW combo drive and you experience recording problems, check for available software patches at the Sonic support website at support.sonic.com. Currently, five DVD-writable disc formats are available: DVD+R, DVD+RW, DVD-R, DVD-RW, and DVD-RAM. The DVD-writable drives installed in DellTM computers can write to DVD+R and DVD+RW media, and can read DVD-R and DVD-RW media. However, DVD-writable drives do not write to and might not read DVD-RAM media. In addition, commercially available DVD players for home theater systems might not read all five formats. NOTE: Most commercial DVDs have copyright protection and cannot be copied using Sonic RecordNow. 1 Click the Start button, point to All Programs Sonic RecordNow!, and then click RecordNow! 2 Click either the audio tab or the data tab, depending on the kind of CD or DVD you want to copy. 3 Click Exact Copy. Setting Up and Using Your Computer 17 www.dell.com | support.dell.com 4 To copy the CD or DVD: · If you have one CD or DVD drive, ensure that the settings are correct and click Copy. The computer reads your source CD or DVD and copies it to a temporary folder on your computer hard drive. When prompted, insert a blank CD or DVD into the CD or DVD drive and click OK. · If you have two CD or DVD drives, select the drive into which you have inserted your source CD or DVD and click Copy. The computer copies the data on the CD or DVD to the blank CD or DVD. Once you have finished copying the source CD or DVD, the CD or DVD that you have created automatically ejects. Using Blank CD-Rs and CD-RWs Your CD-RW drive can write to two different types of recording media: CD-Rs and CD-RWs (including high-speed CD-RWs). Use blank CD-Rs to record music or permanently store data files. After creating a CD-R, you cannot write to that CD-R again (see the Sonic documentation for more information). Use blank CD-RWs to write to CDs or to erase, rewrite, or update data on CDs. Your DVD-writable drive can write to four different types of recording media: CD-Rs, CD-RWs (including high-speed CD-RWs), DVD+Rs, and DVD+RWs. Blank DVD+Rs can be used to permanently store large amounts of information. After you create a DVD+R disc, you may not be able to write to that disc again if the disc is "finalized" or "closed" during the final stage of the disc creation process. Use blank DVD+RWs if you plan to erase, rewrite, or update information on that disc later. Helpful Tips · · · · · Use Microsoft® Windows® Explorer to drag and drop files to a CD-R or CD-RW only after you start Sonic RecordNow and open a RecordNow project. You must use CD-Rs to burn music CDs that you want to play in regular stereos. CD-RWs do not play in most home or car stereos. You cannot create audio DVDs with Sonic RecordNow. Music MP3 files can be played only on MP3 players or on computers that have MP3 software installed. Do not burn a blank CD-R or CD-RW to its maximum capacity; for example, do not copy a 650-MB file to a 650-MB blank CD. The CD-RW drive needs 1 or 2 MB of the blank CD to finalize the recording. Use a blank CD-RW to practice CD recording until you are familiar with CD recording techniques. If you make a mistake, you can erase the data on the CD-RW and try again. You can also use blank CD-RWs to test music file projects before you record the project permanently to a blank CD-R. See the Sonic support website at support.sonic.com for additional information. · · 18 Setting Up and Using Your Computer Using a Media Card Reader (Optional) Use the Media Card Reader to transfer data directly to your computer.

Power Management The Microsoft® Windows® XP power management features can reduce the amount of electricity your computer uses when it is on and you are not using it. You can reduce power to just the monitor or the hard drive, or you can use standby mode or hibernate mode to reduce power to the entire computer. When the computer exits from a power conservation mode, the Windows desktop is restored to the state it was in before it entered the mode. NOTE: Windows XP Professional includes security and networking features not available in Windows XP Home Edition. When a Windows XP Professional computer is connected to a network, different options related to security and networking appear in certain windows. Standby Mode Standby mode conserves power by turning off the display and the hard drive after a time-out.
