Thanks will look into it. The files are not lost on the h/d of the pc. Just on transferring some of them a message comes up saying said file is not at the location when it definitely is. Result is it cannot be transferred to the external h/d for safe storage. Any other suggestions welcome.
Is it possible that the external hard drive is going to sleep while you are not using it and that you need to wake it up before you start your backup procedure? Possibly you should have a look at the external hard drive using Windows Explorer and open a sub-folder before you backup to ensure that the external drive is ready to go.
