Extend Volume - Disk Management

Hi Experts,

I need to extend a volume/partition but the option is not available. I have tried doing it through diskpart but have found the same. what is the partition in green? I assumed this was empty space and I wanted to expand the C:\ drive into it.

this PC is responsible for call recording and was setup AD-HOC years ago. so config is unknown other than its windows 7 Pro 32bit

You cannot extend the C:\ drive because there is NO Unallocated contiguous space next to the C: volume.

You will need to shrink the E: Volume (and Logical Drive = Green), and then move the E:\ volume down the disk, and then the Extend Option will be available to the C: drive.

You will need to use a Third Party Partition Manager, and Make sure you have a backup.

what is a logical drive? and I am very reluctant to use any 3rd party applications on a PC which is responsible for the call-recording.

it supplies an option to reduce the size of the disk from the Disk Management console (shrink Volume...)?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Logical Drive is define as part of the partition.

You'll can shrink the volume, but that will not shrink the logical disk, and hence will not make space for your C:\ drive.

it's very old fashioned to create logical drives these days, most just create partitions (volumes), which is also considered old fashioned.

Big Business Goals? Which KPIs Will Help You

The most successful MSPs rely on metrics – known as key performance indicators (KPIs) – for making informed decisions that help their businesses thrive, rather than just survive. This eBook provides an overview of the most important KPIs used by top MSPs.

What is on your drive "E"? If there is nothing of value on there, you can just first change the pagefile setting so it doesn't use E, then delete E, and after that you can expand your C partition. Leave at least 10MB un-partitioned, or if you want E again, you can create a new E partition after that (just always leave those 10MB un-partitioned space).

or, create a new disk (if virtual), move all the contents to new disk.

delete the old, volume/logical disk.....

Extend C: drive

(partitions are old fashioned, and you are much better having a volume per disk, it's easier to extend them!)
Gary CaseRetiredCommented:
You have an MBR disk, which is limited to 4 partitions.    When you create the 4th partition, Windows creates an extended partition, and then a logical volume within that partition.      The green denotes the extended partition.

If you shrink the volume, the free space will still be within the extended partition.   You'll then have to shrink the extended partition; and then "slide" it to the right so the free space is next to C: -- and THEN you can extend C:

The EASIEST way to do what you want is to simply (a) copy all the data off of E: to another disk;  (b)  Delete E:, and then Delete the extended partition (this option will be available after you delete the volume(s) it contains);  (c) extend C: as much as you want;  and then (d) recreate the 4th partition and the E: volume and copy the data back to it.    This can be done entirely within Windows with no need for 3rd party tools.
While all what was previously said is true, you are likely in a bind given it is highly likely that the recordings are written to the E:\ drive

Config unknown? If you have a login into the system, it is fairly straight forward to identify what is running on the system, where it is being written, etc.
In your place, I would not be making any attempts to make any adjustments until I was fully aware of what was going on the system
The alternative, given this was setup "years ago", is to use a "newer" system to setup as you deem appropriate to fill the tasks this system is providing in the correct configuration, and transition the roles from the current system to the new.  This type of a transition will also provide you with a failback option that others would not if you miss a component that few ever use and did not indicate prior to you taking steps.
i.e. one person on a quarterly basis using a link/reference runs a report possibly/likely unaware of the source. Once you make the change, and that report is needed the failure will be apparent, but without any way to get it back......

Agree that simply copying all of the data could miss something.

There are two "safe" ways to proceed ... but both require that the system be down for a while -- potentially a few hours depending on how much data is on the E: partition.

(a)  Shrink the E: volume as much as you want to (i.e. by the amount of space you need to add to C:).    You can do this in Disk Management while the system is running.
(b)  Now shrink the extended partition so there's no free space "inside" of it
(c)  Boot to a good imaging program (I like Boot-It BM, but use whatever you're comfortable with) and IMAGE the E: volume
(d)  Delete the extended volume (You can do this from your imaging utility)
(e)  Extend the C: volume by the amount of space you freed up with the shrink.
(f)  Restore the volume you imaged in (c)




(a)  Do steps (a) and (b) from #1
(b)  Boot to a Boot-It BM CD (or flash drive) ... select CANCEL at the first prompt; then OK to go to Maintenance Mode
(c)  Click on Partition Work;  highlight the partition that you need to move (the one that contains E: -- the drive letters won't show up here, but you can easily tell from the size);  then click on "SLIDE" ... and choose ZERO free space AFTER the partition.    This operation will take a LONG time -- it has to move all of the data in the partition.
(d)  Reboot to Windows -- you can now simply extend C: in Disk Management

Peggie - and BEFORE playing with the disk / partitions - be sure to have a complete backup - in case something goes wrong

i use the paragon software for making an image  (you can make a bootable cd-or usb stick, so nothing comes on the disk drive

There is a page file on this D drive. Means you cannot move resize it in Windows. But if you disable page file, copy out all data and then delete first D drive. Then extended partition (a green frame around D drive) then you will be able to extend C drive.
