I've been having this problem for a while, but it's getting worse. I'm not sure if it's InCD or my Pioneer 107D.

When I try to back up a file, I'll get errors like "file name can't contain invalid characters", or it simply won't do anything at all. Then I have to erase the disk and it works fine. It used to happen ever few months, but now it's happening every other day or so. It also occurs with TDK and Memorex disks, regardless of age.

Has anyone else had this sort of problem? It's getting annoying.

Thanks.....
