extend C drive with contiguous space

Hi,

I want to extend my C drive but the extended option is greyed out. It's greyed out because I don't have contiguous space. For some reason, Asus decided to allocate 120GB on the F Drive to this primary drive to System Volume Information and the Recyle Bin. This F Drive is continguous with the C Drive.

I can shrink the F Drive but it shrinks from the right of it. There is a program here:
http://www.extend-partition.com/partition-magic/extend-volume-greyed-out.html

that allows to extend the C Drive without continguous space. If I use it then does this affect anything or I'm thinking it'll affect performance. Are there reasons why Microsoft greys out the extension of the C Drive if the space isn't contiguous?

Thanks

If the drive is decently fast, having C in a couple of sections will not hinder performance. I have large files (whole machines) that are not contiguous on my C drive and they work fine. My page file is fixed and a fair distance from working files. No issue. Small fast drives are not hindered by moving around.

can you post a screenshot of disk management?
that tool will move the other partition along with the data in order to get contiguous space after C

your last question is answered in your second sentence...the option is not available because the space is not contiguous. basic disks have a start and end point for the partitions; can't have multiple

Actually it's very simple to just move the D: drive "to the right" so your unallocated space is next to C: ... and then you can easily extend C:

Download the free demo for Boot-It BM [http://www.terabyteunlimited.com/bootit-bare-metal.htm ]

Extract the files form the archive, and create a bootable CD using the MakeDisk utility.

Boot to the CD;  selecting CANCEL at the first prompt; then OK.

Now click on Partition Work.   Be sure you've selected the correct drive (you can tell by the partition structure you'll see);  then highlight the partition that corresponds to D:, and click on "Slide".   Choose 0 space "After" ... and wait for the operation to complete (It has to move all the data on D:, so it may take a while).

Done :-)    Just reboot, and you can now extend C: using Disk Management.   [You could also ReSize it from Boot-It's screen if you want after the Slide has completed.

Hi,

Thanks everyone for your answers! Really helpful.
@John, ok, good to know.

@Seth, I'm attaching the disk management screenshot.

@garycase, ok, will try it. Actually I the main hard drive where C Drive is a 256GB SSD. The F Drive is on this same drive. Then there is around 20GB space which states "Healthy Recovery Partition" which I guess is where the Asus Recovery Disks are.

So if I use the program then F Drive moves to the end it won't affect the last 20GB of hard drive space which is at the end of this main drive, will it?

The partition structure shown in your Disk Management picture doesn't show this extra Asus partition -- is that an HPA?     In any event, there's no problem "sliding" D: to the right to effectively switch the unallocated space so it's between C: and D: (i.e. contiguous with C:).

Boot-It won't move the partition anywhere that it would interfere with other partitions -- it can only "slide" it into unallocated space.

@garycase, Oh, that's fantastic! That's what I need. Ok, great. I'll try it. Thanks. Will have to try it when I'm in Dallas since I'm about to board a flight soon. =)
