I don't have a burner, there are two where I stay and I just get somebody else to do whatever I need. My father however uses his burner for data back up on a daily basis. He is running Win2k Pro at work and he just installed WinXP Home on the machine at home. What he wants to be able to do is maintain 3 up to date copies of all his data files. In other words at the end of the day at work he will update a CD-RW with anything he has changed. Take it home and put it on the home machine. Then if he makes any changes at home, he'll burn the change to that same CD-RW and then take it back to work the next morning. I believe he is running DirectCD 4 on the Win2k machine right now. And XP's built in software will read, but won't write to discs created by DirectCD. The reverse is also true. He's wanting me to get him prices for DirectCD 5.1, but the little reading I've done here would say otherwise. What would be the best option for him?
