What Are The Requirements To Merge Partitions

By Saturn2332 ·
Well, I'm now in the role of IT Department for a small company. I also perform instrument driver code development and find my present XP machine lacking.

Someone before me set a 40 GB partition (c:\, NTFS, basic, system) for the XP OS and installed Vista, dual boot, on a 60 GB adjacent (d:\, NTFS, basic) partition. There is also an e extended logical partition of 180 GB for data and code development.

My problem is this: Following all the guidelines I've eliminated the dual boot Vista OS and reformatted d. However, everything I've tried has not been able to merge d into c. Yes, that includes 3rd party partition programs.

Is this because:
1) I've only 8% free space on c and one cannot even defrag with that?
2) Are there undiagnosed bad sectors (did chkdsk) on c or d preventing the merge?
3) Does the presence of an adjacent to the right 'extended' logical partition (e:\) prevent a merge?

Has anyone encountered this before and is there a solution? Yeah, I can uninstall AutoCAD, Pro-E and Solidworks to make >15% free on c if necessary. Can put them back later from CD.

Need to have 3 CAD software programs AND National Instruments LabVIEW 2009, 2010 and 2011 plus all the attendant DAQ and Serial drivers installed on this machine to bring our codes and drawings forth into Windows 7 with retroactive XP compatibility.

Could use Symantec Ghost (or something similar) and a big USB drive to re-make the PC (still a good quad core machine) but that is a lot of extra effort...

Thank you for responding to this post.

Warm Regards,
PS: Please help, I'm only a Chemical Engineer...

Try reposting this in the 'Q&A' forum. The 'Discussion' forum is for matters of general discussion, not specific problems in search of a solution. The 'Water Cooler' is for non-technical discussions. You can submit a question to 'Q&A' here:


There are TR members who specifically seek out problems in need of a solution. Although there is some overlap between the forums, you'll find more of those members in 'Q&A' than in 'Discussions' or 'Water Cooler'.

Be sure to use the voting buttons to provide your feedback. Voting a '+' does not necessarily mean that a given response contained the complete solution to your problem, but that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours. If they have a ready source of reference available, perhaps won't need to repeat questions previously asked and answered. If a post did contain the solution to your problem, you can also close the question by marking the helpful post as "The Answer". .

In the mean time you'll need some specialized software to do this as it's not a part of the XP Operating system. Something like Partition Magic or similar Partition Management Software.

Did that already.

Tried Partition Magic and it did not work.

Oh, this is easy!

You cannot merge partitions across disks.

Perhaps you can tell us what you are actually seeking to accomplish by doing this.

One DIsk

One Physical Disk and still cannot merge partitions. Is this because there is an extended partition present?

Why do I want to do this? The XP OS was partitioned to ~40 GB when a Vista trial was installed. The Vista partition took up ~60 GB but I've removed Vista and want the space back in the XP OS partition on C.

At present, there is only 11% free space on C and less than15% free space cannot be de-fragmented.

I need to have National Instruments (NI) LabVIEW 2009, 2010 and 2011 all installed on this PC along with all the attendant drivers. The applications can be installed into a Program Files directory on what was the Vista drive (D:\) or the extended 300 GB partition (E:\) that is used for code development files.

Unfortunately, there is no way to tell the OS during installation of the (NI-DAQmx, Serial, VISA, Vision, RIO, etc...) driver packages which drive to install on. They MUST go onto the OS drive. I'm now out of room and cannot defrag unless I uninstall MS Excel (etc.) but I need that...

Yeah, that Is why I need to expand the OS drive.

Our CEO allowed me to purchase a fine new 64 bit T7500 workstation with W7 OS (+ XP virtual PC) to bring our codes into the present but I still need an XP only PC to test them on as I must make the application and installer test compliant back to the last OS supported by Microsoft. That is now XP.

If all else fails I can use a Symantec product called Ghost to image all partitions, delete them, repartition to the size needed, reformat then install the images. That is a lot of extra work though when Partition Magic or the command line should work.

Warm Regards,
