I have been putting data on a CD-R disk since 2008 and all of a sudden it won't read in my computer (laptop). Nothing will come up. I have been viewing this data for months so I know there's something on it. And by the same token, the CD player plays all the other disks that I use which leads me to believe it's not the computer. Any input you have on this problem will be greatly appreciated. The disk is a intricate part of my job.
This page has an ActiveX tool called Automated Troubleshooting Services which will run and fix the disk problems. After running it, I was able to read my CDs & DVDs. I believe it fixed the UDF drivers so the drives would properly recognize discs containing UDF. I am running XP Pro SP3.
