Thanks for the replies. I have spent some time on this matter my self. I now have 104 files in total, 49 are still good, 45 went off on the 13/1/11, 8 on other dates in January 2011 and 2 much later.
Only near 50% not 70%!
None of my photos are bad but all of my music on the computer is bad, If there are say 25 songs in a folder, it will show, say, 7 bad remove these bad ones and play and another batch goes bad, over and over.
I never had auto back-up on, I do now. I also did Chkdsk but it showed no problens that I saw.
I agree that it is not just in the OOo system, but I still need to try to find out the problem and if any-one else has had same problem.
With the music going off like that does it mean that the Virus(if that is what it is) is still active.
If I convert these good files to excel ect and transfer to my other computer could that infect that computer.
