Hey all, I hope this is the right forum for my question, but feel free to\ndirect me elsewhere if not.\n\nI posted this question on another Vista forum but, despite other posters'\nefforts, I could not solve the problem. So I hope I have more luck here.\nSimply, the trouble I'm having is that I need to extend a partition on my\nHDD. When I first created the partitions when I put the computer together, I\ndidn't leave enough space on the partition that holds the OS, because I\nforgot that it would need room in the future for things like updates. So,\nwhen I tried to install Service Pack 1, I found that there was not enough\nspace for it.\n\nFor some reason, the disk management utility will not allow me to extend\nthat particular partition, even though I definitely have free space on the\ndrive. (Just to make sure of that, I've shrunk other partitions and then\ntried to add that now-free space to the OS partition, but still no luck.) I\nreally have no idea what else to try, because I'm not all that technically\nsavvy to begin with...\n\nLet me know if I can provide any more details to help with an answer. Thanks\nfor reading.
