Paul Erickson:
I keep getting an "Insert a writable or blank disc" message
Andrew Kelly:
I discovered that the 3 disks which I been trying to use had been, er... grabbed from the wrong stack. They weren't blank.
So, user error on my part.
Although, to my defence I have to say that absolutely no helpful message is returned. Something as simple as "disk not blank" would have saved me a ton of stress and a wasted hour.
*You* didn't get the message about inserting a *writable* or *blank* disc? The inference is that the one in the drive *isn't*.
