Acronis True Image 9 to dvd+rw

hi
i am using acronis true image to do a full drive image to a
dvd+rw.
However it keeps asking me to format dvd+rw because windows xp home can not read disc? and needs formatting.
Do dvd+rw need formatting first?

thanks in advance
cheers kev

In a way yes they do. When you first use a +r/w the programs usually says doing a format before burning. Only happens once per new disc. Your burn software should be doing this for you but I never used Acronis

How can I use Acronis True Image 9.0 to write images directly to DVD discs?
Acronis True Image 9.0 is capable of writing to a DVD disc in Windows if UDF packet DVD-writing software is installed and the DVD disc is formatted. If a DVD disc is not formatted, Acronis True Image 9.0 will ask you to format it.

You need a Drive Letter Access (DLA) UDF packet writing driver so that you can format the DVD and the computer can see the disc. Acronis True Image 9.0 currently supports the following DVD-writing software:

Roxio Drag-To-Disc — a part of Roxio Easy Media Creator
Ahead InCD — available for free on the Nero site for Ahead Nero users (and usually is shipped with Nero)
In general, Acronis True Image 9.0 also supports other UDF packet DVD-writing software, but the two above are the most popular and they have been tested and approved by Acronis.

To make the DVD disc writeable in Acronis True Image 9.0, you should do the following:

Install UDF packet DVD-writing software.
Format the DVD discs.
Start Acronis True Image 9.0, insert the formatted DVD disc into the DVD burner and create an image.
The images from the DVD disc can be restored both in Windows and by means of the standalone version of Acronis True Image 9.0.
There is also a two-step method for writing to DVDs. Acronis True Image 9.0 can create an image of a hard disk/partition as a single file on the hard disk itself, and then you can copy the file using your own DVD-writing software to the DVD disc. We recommend you to set the image archive splitting size to 2,000 MBytes (2 GBytes) on the “Image Archive Splitting” screen, as generally the maximum size of a file stored on a DVD disc is 2 GBytes.
