I've used an external USB drive for a long time, with a small win32 partition and two ext3, for use on gOS (Ubuntu), Mac and XP for the same reasons that you give. This is because I move around a bit, and use two or three static desktop computers, so the data moves with me.<br>
<br><br> The only strange thing I find is that sometimes Ubuntu will mount one partiton as "disk" another as "disk-1" etc then next time, it will change the order. That might not present a problem to most people, but I use programmes such as Picasa with photos on the disk and thunderbird with signature files. So if the partition names are swapped over, these programmes cannot find the files and have to be reset. There seems no reason for the change - completely random, although i'm sure that someone will know why this happens. Greg<br>
