Formating DVD+RW Disks

  Trixster 23:35 03 Feb 2003

I have been using DirectCD from Easy CD Creator for my CD-RW for sometime to format the disks and enable drag & drop of files onto the CDRW. Does anyone know if I have to format DVD+RW in the same way before using them? I note that whilst the capacity is said to be 4.7GB, the DVD+RW appears to be only approx 4.3GB. Is this because it is already formatted with the file structures etc?

If you want to drag and drop, yes, you need to format the DVD+RW for packet writing, unless the disk comes pre-formatted. The DVD+RW rewriter should come with software which enables you to do the formatting. +RW supports background formatting, so the initial formatting should not take too long.

As to the capacity of only 4.3GB, some people say it's because the disk has been formatted, but the other explanation (and more likely) is the same reason for the difference between hard disk size and what Windows reports it to be. Windows uses the binary system, so 1KB = 1024 Bytes, and not 1000 Bytes. +RW disks have a capacity of 4.7 million Bytes (=4.37GB in Windows).
