When trying to copy files (Excel) from hard drive to CD-RW disc I keep getting the message: Invalid MS-DOS function (Try again?)

This has only just started, I've never had the problem before!

Does anybody know what's causing this and what I need to do to fix it?

Many thanks
Colin

We need a lot more information. What OS are you using?

Are you using Windows to copy or are you using a third party program to burn the files onto the disc?

Hi, Colin, and welcome to the forum.

It's important to note that copying to a CD isn't like copying to a floppy or flash drive--even if you have a version of Windows that supports writing to optical drives. The CD format was designed to be read-only, and even erasable CD-RWs can't act like other kinds of storage devices.

Anyway, we can give you more precise advice after you answer rgreen's questions.

Thanks for your replies.

I'm using Windows Vista (not sure exactly which version)

It's never been a problem before today, I usually just pop a CD-RW into the disc drive scroll down Excel files and select send to: dvd rw drive and it does it! Or, I just copy & paste.

I can't understand why it has suddenly started giving me this message?

You can get that error if you have a bit of file system corruption. Try running CHKDSK /F from the command prompt. (Search cmd) You may have to right click on CMD in the search results and run it as administrator if you are running Vista. It won't be able to get a lock on the system drive, so will offer to run on restart.
Perhaps an easier way to do this is to right-click on the C drive in Windows Explorer or Computer, choose Properties, the Tools tab, "Check Now" button, and check the box beside "Automatically fix file system errors".
