windows xp backup

[con-amca]

My computer has an A: drive (3� inch floppy) and a D:
drive (CD-ROM). I want to back up files onto the D: drive, but when I invoke the Windows XP backup wizard, and arrive at the point where it invites me to choose a destination, I can choose between "3� floppy" or "A:\", which of course is no choice at all. How do I change this destination to "D:\"? My computer support provider (Evesham) is no help at all.

if it's a CD-ROM drive, you can't use it

CD-ROM stands for Compact Disc - Read Only Memory, hence it's not a writer, so you can't burn any CDs with it

Thanks for your response, ugly_bob. And sorry, I misled you - I should have said CD-R/CD-RW drive. I can write to the drive by copying, but I can't get the Windows backup to write to the drive. Maybe I should just copy the files, but I can't see the point of having a backup facility if you can't use it.
