George/Kevin, What you want to do is not really possible - that is, when you write to a CD/DVD it is not possible to just delete and recopy a file over the top. There are two workarounds, one which involves recreating the disk as a whole, which is what you are doing, or the other way is to use a packet writer such as InCD (Nero) or Direct Disk (Roxio) to get the disk acting as a floppy drive. However, you should be aware that sometimes there are issues with packet writing software, i.e, it writes to a cache which in turn writes to the disk. If you have a problem which damages the cache in memory, you can loose data. I have seen quite a few instances of this happening both using Nero and Roxio, so don't tend to use this method, though later versions are a lot better in this respect. Thanks. Andrew. -----Original Message----- From: access-uk@xxxxxxxxxxxxx on behalf of George Bell Sent: Thu 31/08/2006 14:40 To: access-uk@xxxxxxxxxxxxx Subject: [access-uk] Re: problems with altering data discs i've created Kevin, Is it possible that you have "No Multi-session" selected?
