I have a computer with a CDWRITER 2410. My kids can use it to 'copy' cd roms or create a cd-rom. I want to use it as an additional disk drive. Ideally, I would like to keep my mail on one disk, downloaded items on another, etc. I am unable to do so however because when I try, I get the message 'Disk D: is unavailable'. None of my software - Alcohol 120%, etc. - will function in the manner I want to use it. I am hoping that someone will have fought this battle and won. Thank you.
