I am off round the coast of Britain in my elderly motor caravan to gather material to write a guide to camping and caravan sites with a view of the sea. I want to be able to back up to as CD while I am on the road in case I lose the lap top. My Toshiba 1000 laptop does not have a CD-RW facility and a module that would fit costs over £300 so I opted for an external Iomega CD-RW to connect to my laptop. The discs I have are 650 Memorex CD-RW and I have had problems getting them to run. Firstly the Iomega external CD-RW said that I must format the discs but when I tried a message came up saying there was no disc in place. Eventually when I managed to download a file from the laptop to the external CD-RW it would not run on my desktop PC. I have been told that some external CD-RWs are not always compatible with Desktop PCs. I have also been told that some CD-RW discs are better than others so I wonder if it the Memorex discs I have are up to the job. My question is: Does any one know of an independent review of CD-RW discs on the web or am I asking the wrong question?
