.12.2 Nero level indicatorThe level indicator is at the bottom of the Nero main window.The level indicatorallows you to tell whether the data you have selected will fit on the disc.As datais normally measured in megabytes and audio data in minutes of playing time,the Nero level indicator switches between megabytes and minutes dependingon the type of data being written to CD.A blue bar in the level indicator showsthe size of the current compilation.Standard CDs normally have a capacity of 650 MB (or 74 minutes).There arenow blank CDs available with a capacity of 80, 90 and 99 minutes.Thereforethe capacity of blank CDs is currently between 74 and 99 minutes.The Nerolevel indicator attempts to accommodate this by showing a yellow line at 74minutes (or 650 MB) and a red dashed line at 80 minutes (or 700 MB).If you want to move these markings, you can do so using the Nero Preferencesmenu item.See the section 'Modifying the Nero level indicator'.You should note however that the value you enter here only affects the displayof the level indicator.It is not possible, by changing these values, to create extrastorage space where none actually exists.If you want, you can also switch offthe display of the level indicator from the Nero Preferences dialog box.Nero Miscellaneous " 108 Although the Nero level indicator is useful, as a result of the following problems,its accuracy cannot be guaranteed:With the exception of the continuation of multisession CDs, in most cases thedestination CD is not put in the recorder until a later stage, which means thatNero cannot yet tell whether the compilation will fit on the destination CD.The sizes given on the level indicator must therefore be based on theassumption that an empty CD is being burnt.In the case of ISO compilations, the structure of the data to be burnt isrelatively complex and dependent on a large number of different factors.Thecreation of this type of structure is too time-consuming to be done in realtime.This means that until the burning process actually starts, it is notpossible to determine exactly how much space will be needed for the data onthe CD.The sizes given on the level indicator are therefore just a goodestimate of the space needed by a compilation.12.2.1 Modifying the Nero level indicatorIf you want to modify the level indicator, follow the instructions below:1.Go to the File menu and choose the Preferences item.2.On the General tab, enter the number of minutes for the yellow and redmarkers.3.Click on the OK button to save the settings and close the dialog box.12.3 Automatic detection of CD/DVD-ROM drives12.3.1 BackgroundThere are so many different types of CD/DVD-ROM drive on the market that it isnot possible, for reasons of time and availability, to test and provide specificsupport for every single CD/DVD-ROM drive.Nero can already identify a largenumber of common CD/DVD-ROM drive types, but providing support for all thedrives available is not possible for the reasons given above.For this reason, Nero has the Autodetect CD-ROM option on the Recordermenu for those people whose CD/DVD-ROM drive is not supported.Once theCD/DVD-ROM drive has been identified successfully, it can be used as an inputdevice for CD fast copies and for saving tracks.This automatic detectionprocess should in most cases allow the use of a drive which is not normallysupported by Nero.12.3.2 Autodetection of CD/DVD-ROM drivesUsing the Autodetect CD-ROM option, Nero attempts to identify the specificproperties of the CD/DVD-ROM drive by sending commands to the drive andchecking the data returned by the drive.However, this process does entail somerisks, as there are no definitive standards for the commands used to controlCD/DVD-ROM drives.Sending unsupported commands to a CD/DVD-ROMdrive can cause the computer to crash.For this reason, we recommend that youNero Miscellaneous " 109 close all other programs and save important documents before starting theautodetection process.1.From the Recorder menu, choose the Autodetect CD-ROM menu item.Adialog box appears which contains a list of the CD/DVD-ROM drives notcurrently supported by Nero, from which you can select the drive you have.2.In addition you can also set the CD/DVD-ROM bus type.If this is already seteither to SCSI or to IDE, you should only change this setting if you are surethat it is wrong, as Nero takes the information from the CD/DVD-ROM driverand therefore, it should be correct.If you have an IDE CD/DVD-ROM drive,the 'Commandset' list box contains only one line, and the setting cantherefore not be changed.This is because IDE drives are more standardizedthan SCSI CD-ROM drives [ Pobierz całość w formacie PDF ]
