How large are your two partitions? Someone else may need to correct me, but the only way I am aware of that you can repartition your hard drive is to reformat it - which wipes everything off. I am wondering why it is partitioned to begin with - XP doesn't have the hard drive size restrictions that earlier versions had, well, most people would not have a problem with it.
Of course you will be sure to back up your documents, etc, on your external before you go![]()
