Hello, I need to re-partition my hard drive but I am afraid to do so. I have 2 physical drives in my computer. My C: is the only one partitionned into 5 partitions. My D:is a whole drive not partitionned and I dont want to touch it. But I would like to increase the space on C: by combining it with partion E: If i do so, would I need to re-installed the OS? I am using Partition Magic 4 from Power Quest, but they dont any information who to increase the space of a partition without losing or re-installing it. Can anyone advise on this ...what is i should do?
