I'm using Windows 7 with the built in Disk management application. When doing so, I'm perfectly fine to shrink C partition, but I'm not able to extend the D partition with the space taken from C partition. Why is that? Is there a workaround? I've also posted some screenshots (Norwegian), I assume that there should be no problem reading the screenshots as you have the same menus on English. If not, let me know so I can change to English language and re-post the screenshots. I would also like to add I work with computers daily, is there any advanced troubleshooting that can solve the issue, let me know. http://bildr.no/view/626294 http://bildr.no/view/626297

Using the built-in Shrink/Extend tools, you are only able to Extend a partition using contiguous, unallocated space that appears to its right, otherwise the option is greyed out. However, by moving the unallocated space from partition to partition, any standard partition can be extended. What you need to do is:1. Format the 42.65GB and allocate, say, letter L2. Copy the contents of the D drive to L3. Delete partition D4. Extend the L partition to incorporate the old D5. Reletter L as D

When I tried to make an partition for the 42.65GB it gives me the following error code: Invalid package name

Actually, the question you asked has discussed for a long time, and many computer users are not very sure how to realize it perfectly, certainly the minority of computer experts included. I am very lucky, and I got the useful information about the efficient method to work it out. So, now, maybe after you do as I said, you will find that extend partition is not difficult any longer. Go and see the website I linked.
