12 disc burning tips

Squeeze more data onto a disc, burn audio discs and more

You could be forgiven for thinking that CDs and DVDs are outmoded technologies. With flash memory getting cheaper and the cloud becoming ever more pervasive, storing data on circles of plastic-coated aluminium seems little better than chiselling ones and noughts on slabs of stone.

But it's not that simple. How will the cloud help if your PC won't boot? Is a thumb drive any use if you want to play a movie in your vintage DVD player?

Like it or not, CDs and DVD still have their place in the world. They're cheap, easy to make and can often work as a brilliant bridging mechanism between different devices and data formats.

Here are 12 disc burning tips to help you squeeze more data onto a disc, burn audio discs and more.

1. How to make a data disc

Windows' own data disc burning routines can be slow and frustrating, and don't always produce a disc that can be read by other devices. You're better off using a dedicated disc-burning program like CD BurnerXP or ImgBurn.

These make burning data to disc simpler, and avoid the need to cache the whole disc contents to a temporary folder in the process.

If you're using CD BurnerXP, launch the program and choose 'Data disc'. Browse to the files or folders you want to include and drag them onto the lower pane. Check the indicator to see how full your disc is. Click 'Burn' to write your files to disc.

In ImgBurn, choose 'Write files/folders to disc', then drag the files you want to burn into the left-hand pane. Click the 'Build' button and the program checks your compilation, offering corrections to make the disc compatible with most devices. It can also verify the data on the disc after burning it.

2. How to overburn a disc

Overburn

Launch CD BurnerXP, insert the disc you want to write to, and add the files or folders you want to burn. If the data size exceeds that of the disc by only a small amount, click 'Burn' and then choose 'Overburn' when you're warned about the mismatch.

If the disc burns successfully, test it to see that all the files have been transferred. The smaller the overburn, the less likely you are to have problems.

3. How to burn a secure disc

The simplest way to encrypt files on a disc is to use TrueCrypt. Select 'Create volume | Create a file container | Standard TrueCrypt volume'. Choose 'Select file' and browse to where you want to store the container file. Enter a filename and save it. Provide your password and opt to format the volume.

You can mount it using TrueCrypt with your password, and use it to store sensitive files. Once you've added your files to this volume, burn the container file to disc using your disc-burning software.

4. How to make a bootable DOS disc

You might want to create a DOS boot disc if you have old games that only run under DOS. To do so, you need a PC with a floppy drive and a DOS boot disk, which you can download from www.bootdisk.com.

Use ImgBurn and choose 'Mode | Build'. Put your DOS boot floppy into the floppy disk drive. Choose 'Advanced | Bootable disc' and select 'Make image bootable'.

Choose 'Floppy Disc 1.44MB' as the emulation type and select your floppy drive under 'Extract boot image'. Add any other files you want to include. Insert your CD and click 'Burn'. Boot from this disc and it acts like the A: drive.

5. How to burn dual layer discs

Burning data to a dual-layer disc works in much the same way as creating a data disc, as long as you use a disc-burning program that supports dual-layer burning, and have a dual-layer capable disc and drive. However, if you want to create a video disc, you'll need to decide where the layer break comes, because there will be a slight pause here during playback.

In ImgBurn, choose 'Build mode' and add the DVD video files that you need for your project. Click the 'Burn' button and provide a volume label. ImgBurn shows some suggestions for the layer break position. Select one and click 'OK' to proceed.

6. How to burn an audio CDs

CDs that play in standard CD players need to be in Compact Disc Digital Audio format. Most music files are stored on a PC in compressed forms and need to be converted. Several programs are capable of doing this, including Windows Media Player, but CD BurnerXP provides a very simple interface.

Launch the program and choose 'Audio disc'. Click 'OK'. Browse to the audio files that you want to include in your disc and drag them into the lower pane in the order you want them to appear on the CD. Insert a CD and click 'Burn' to produce the final disc.

7. How to combine VOB files

DVDs recorded on camcorders or home DVD recorders save their contents in VOB, IFO and BUP files. The files with the extension VOB that contain the video, while the other types include disc information and backups.

You can play VOB files in VLC media player, but your files won't necessarily match up with chapters.

To get a full video, you may need to combine several VOB files. There's a simple program that will do this, called Join VOB Files Tool. Get it from here, then unzip the file and launch the executable.

Click 'Add VOB file' and browse to the files you want to join. Click 'Change file name' and supply the name and location for the joined up file, then click 'Join VOB files'.

8. How to burn a Blu-ray disc

Blu-ray

To burn a Blu-ray disc, you'll need the disc itself and a drive capable of writing to it. ImgBurn supports Blu-ray recording. Launch it and choose Write Files/Folders to disc. For a data disc, add whatever files and folders you want to the 'Source' box.

If you have a video Blu-ray disc authored, you should have a folder labelled 'BDAV' or 'BDMV', and one labelled 'CERTIFICATE'. Browse for these and add them to your compilation.

Now select 'Options' on the right-hand side, then 'Data Type MODE1/2048'. For 'Filesystem' choose 'UDF', and for 'UDF revision' select '2.50'. Tick the box marked 'Recursive subdirectories'.

Now, on the 'Information' tab, click 'Calculate' to check you have enough space. Click 'Build' and provide a volume label when prompted.

9. How to create recovery files

Recovery

Whenever you burn a data disc, you're likely to have some spare space. You could use this to store other files to ensure each disc is full up, or you could use it to better advantage by storing recovery files for the data that you've already put on your disc.

QuickPar is a data verification and recovery tool that lets you create recovery files from the originals. If anything goes missing, you can use these recovery files and what's left of the data to reconstruct the missing bits.

Launch QuickPar and click 'Add files'. Add all the files that you want included on your disc. Drag the 'Redundancy' slider until the data size matches your spare space. Click 'Create' to produce the PAR2 files. Once complete, return to your disc-burning program, add these PAR2 files and burn the disc.

10. How to restore from PAR2 files

Launch QuickPar and click 'Open'. Browse to one of the PAR2 files alongside the data that you copied from your damaged disc.

The software will detect any missing or damaged files and show them as it scans the data. As long as not too much data has been damaged, QuickPar can recover what's been lost. Click 'Repair' and wait for the program to restore the damaged files to their rightful place.

11. How to read damaged discs

If you find that a CD or DVD no longer reads properly and there are no visible fingerprints or scratches, you may be able to rescue some or most of the data using the free version of ISO Buster.

Insert your damaged disc and launch ISO Buster. Click 'Refresh' if it isn't detected. You'll see each session of recording on the disc. Choose 'File' and pick a session. Choose 'Extract session | Extract user data'. Provide a location to save this to disc. You can then open the image and restore intact files.

12. How to convert to ISO

ISO recorder

Install ISO Recorder, which is available from here. Insert the disc you want to convert, right-click it in My Computer and choose 'Create image'.

In the resulting dialog, ensure the right drive is selected and browse to the location where you want to save the image file. Provide a filename. Click 'Next' and wait as the ISO image is generated. When it's complete, click 'Finish'. You can now browse to your ISO disc image file.
