This is most likely a very basic thing - I´ve searched but haven´t found anything that gives me exactly the answer I´m after, so if this has already been discussed I´m sorry for bringing it up again... I have a 1.5 GHz PB with this superdrive: MATSHITA DVD-R UJ-825: Capacity: 7.68 GB Manufacturer: MATSHITA Model: MATSHITA DVD-R UJ-825 Revision: DAM5 Serial Number: Drive Type: CD-RW/DVD-RW Disc Burning: Apple Supported/Shipped Removable Media: Yes Detachable Drive: No BSD Name: disk1 Protocol: ATAPI Unit Number: 0 Socket Type: Internal OS9 Drivers: No I can burn DVD-R fine. I´ve also burned onto DVD-RW fine, but when I want to burn over them, the drive won´t accept them as writable. I´ve searched around a bit, and found conflicting info, not all of which I understand completely. I think I´ve understood that I need new firmware to do this, but that adding firmware when you don´t know what you´re doing can mess up the drive completely and void the warranty, and I´m not willing to do that. So what´s the deal? Do I have to somehow erase the discs? Is new firmware (or a new PB) the only option to do what I want? Or can´t my drive burn over previously burned DVD-RWs no matter what?
