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
Hyper-Threading is an Intel
®
technology that can enhance overall computer performance by
allowing one physical processor to function as two logical processors, capable of performing certain
tasks simultaneously. It is recommended that you use the Microsoft
®
Windows
®
XP Service Pack 1
(SP1) or later operating system because Windows XP is optimized to take advantage of
Hyper-Threading technology. While many programs can benefit from Hyper-Threading, some
programs have not been optimized for Hyper-Threading and may require an update from the
software manufacturer. Contact the software manufacturer for updates and information about
using Hyper-Threading with your software.
To determine if your computer is using Hyper-Threading technology:
1
Click the Start button, right-click My Computer , and then click Properties .
2
Click Hardware and click Device Manager .
3
In the Device Manager window, click the plus (+) sign next to Processors . If Hyper-Threading
is enabled, the processor is listed twice.
You can enable or disable Hyper-Threading through system setup. For more information on
accessing system setup, see page 96. For more information on Hyper-Threading, search the
Knowledge Base on the Dell Support website at
support.dell.com .
