Dear all, sorry for my poor english, I hope you all may understand what I
mean and helping me.

I often use my windows xp for dvd-ram backup before, last week I've upgrade
my computer and bundled with Vista Ultimate.

At first, I've tried to format my DVD-RAM in vista (with the My Computer
Drive function in UDF 2.01), then I've backup serval files in my DVD-RAM
easily (just like harddisk drag n drop) with the default vista system driver.

But few days before I've reinstall my vista by using the RAID harddisk, when
I wish to copy my files to DVD-RAM, I've found that the DVD-RAM disk was
change to DVD-ROM!

I've never change my disk booktype to DVD-ROM (and don't know how to change
when using in My Computer), and now all my old DVD-RAM disks which I've been
created at win xp were loaded as DVD-ROM!

I've found in the kb center where win xp can disable the "Burning CD"
function for DVD-RAM, but I cannot found this option in my vista, and no
solution for vista, could anyone helping me in urgent? Thank you very much!
