Hi Bob,

Thanks,

I am not sure what the partition size on the external drive is and the PC is over 4 years old, It's a gateway with a pentium 3 prcessor.
But the problem is certainly not the externaql drive. I have been thinking that the Motherboard is up the creek for several weeks as it is doing some starnge things and each time I turn it off I get an error message saying that I can click on it to shut down at once or let it finish what it is doing.
So I beleive the only soution will be to get a new PC or a new Motherboard for this PC!
Strange, because I have been able to save mp3 files from LW to the new disk and have had the "Disk Problem" message before. This suddenly stopped and I could download fine for about 3 weeks and then the error message came back again.
But thanks for your help which I really appreciate.

Laurence.
