Hear ye, hear ye! So it falls to pass, fair Netriders, that I must call forth aid from the more knowledgable computarians amongst you! Backstory: New computer: install XP - discover problem with a stick of RAM. Change and install RAM [all good] reformat and reinstall Windows XP: computer runs great. I THOUGHT when I reformatted and installed, I formatted the same partition I used the first time... perhaps I was wrong. I'm meant to have a 320gig HD, but C: says Total Size = 127 GB. Here's what Disk Management tells me: Now the questions! 1) Am I able to add that unallocated HD space to C: ? 2) If I'm not, should I create a new partition in that unallocated space? 3) If I create new partition, and do not select a new drive letter etc; will the computer act as though it just has one big partition and run without problems, even though it does have 2? OR 4) Do I just have to bite the bullet, make a new drive in that partition and store non-critial items like music, games etc. there? I guess my other option is to reformat AGAIN and make sure to only get 1 partition this time, but I'd prefer to avoid mucking around doing that if I can. Advice both looked forward to and appreciated!
