Setting Up and Using Your Computer 15 www.dell.com | support.dell.com Copying CDs and DVDs NOTE: Ensure that you follow all copyright laws when you create CDs or DVDs. This section applies only to computers that have a CD-R, CD-RW, DVD+RW, DVD+R, or DVD/CD-RW combo drive. 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. NOTE: Most commercial DVDs have copyright protection and cannot be copied using Sonic RecordNow. 1 2 3 4 Click the Start button, point to All Programs Sonic RecordNow! RecordNow!. Click either the audio tab or the data tab, depending on the kind of CD you are planning to copy. Click Exact Copy. 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. 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 without changing your method of recording (see the Sonic documentation for more information). Use blank CD-RWs to write to CDs or to erase, rewrite, or update data on CDs. 16 Setting Up and Using Your Computer 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. · · Hyper-Threading NOTE: Hyper-Threading is supported only on computers that have 3.06-GHz (or higher) microprocessors installed. Hyper-Threading is an Intel® technology that can enhance overall computer performance by allowing one physical microprocessor to function as two logical microprocessors, capable of performing certain tasks simultaneously.

All devices require a driver program. A driver acts like a translator between the device and any other programs that use the device. Each device has its own set of specialized commands that only its driver recognizes. Dell ships your computer to you with required drivers already installed--no further installation or configuration is needed. Many drivers, such as the keyboard driver, come with your Microsoft® Windows® operating system. You may need to install drivers if you: · · · Upgrade your operating system. Reinstall your operating system. Connect or install a new device. Identifying Drivers If you experience a problem with any device, identify whether the driver is the source of your problem and, if necessary, update the driver. 1 2 3 4 Click the Start button and click Control Panel.
