Thanks Ian, have just realised I don't have a CD for Xandros (on the machine) was getting mixed up with one I acquired from PC mag, which is Ubuntu.
That shouldn't matter, as long as you're running from a Live CD (or USB key, or floppy) that has gparted on.
There are specialist Linux Live CDs for system recovery etc which have more 'tools' on.
You might also look for a local Linux User Group.
