I've tried overburning using Nero (latest 18.104.22.168 and 22.214.171.124), but when it finishes writing the Leadout, it says 'Invalid writestate...', and the disc is not readable (and I've tried different media and different overburn sizes, from 704MB to 715MB, same thing). This happens both when copying an overburned disc and when creating a data CD. Overburning does work however with CloneCD and Disc Juggler, although the drive does make a strange 'pause' just before the 'Success' message appears, the same thing happens with Nero, but instead it displays the error message I mentioned. Overburning used to work like a dream with every single program when I had my old GCE 8160B, so I'm a little concerned.
Am I the only one having this problem with the GCE 8240B?
