Read only files

I have recently copied some GPS fishing files from floppies to CD/RW. Although the floppies are not tagged read only files,once copied, the CD is read only.

I can't add anything new nor will the system allow me access to uncheck read only. It didn't use to be this way.

My system is windows XP and the GPS numbers are in an Andren.Com program I have used for 15 years.

Is there a windows tag that causes this?
