I'm on Win 98SE and have never been able to back up my system, but after being told by my PC 3 times in the last week that I have a bad sector on my drive, I thought I had better try again. I bought 25 CD-R80 discs and started trying to backup. I followed the instructions onscreen and away it went, ' to my surprise '. After an hour or so it asked me to insert another disc as the current one was full, and that is the problem ? I tried every disc in the box I bought, but every time I put one in it's drive up popped the message : ' This media is part of the current backup and cannot be overwritten. Please insert another media to continue '..? What is going on, what am I doing wrong, why don't I understand ? Hmmm ? A day has passed with no answers, I got it wrong yet again ??
