For Jim, On my CD-R system (H-P), when I eject a freshly written CD, I am given a choice of leaving it 'open' or 'closed'. 'Open' in this sense means that I can continue to read and write to it but only in a CD-R (RW) drive. 'Closed' means that it can be read in most CD drives, including CD-R drives. At this point however, it cannot be further written to unless reopened for that use. Sadly, these options are not so clearly explained. If this is the trouble that your friend is experiencing then I believe the answer requires that he do the following: 1. Put his CD in the CD-R drive. 2. Start his CD-R system in 'Create a CD' mode and follow the instructions to make it writable(sp?) again. At this point, it must be left in the CD-R drive if alterations are required either manually or by his anti-virus program. It can later be made 'read only' in another step. What is puzzling here however, is how a virus got on a disk that was 'read only'. Assuming access is the problem, a second method of dealing with it is to copy the entire CD to the hard drive, repair the problem and then write the corrected data to a new CD. In this case, it is important that the 'program' not be run or used so as to avoid the possibility of spreading whatever virus problem there may be. I am forwarding the comments I have received from the Wx Forum. I don't know if the suggestions are helpful, as I may not have interpreted the problem correctly. Is it possible to read the disk at all? I presumed that the disk was closed to be read only before this problem occurred? Regards, Ralph Strong
