Windows 10: Unable to resize partition - Virtual Disk Manager, Access is Denied.

I am trying to resize a partition that contains the OS files. When I try to use the Disk Management interface, I am able to see the partition, right click and select Extend Drive. Walks me through the screens but returns "Virtual Disk Manager, Access is Denied" error when I hit Finish.




I have tried taking ownership of the C drive and all the sub folders, tried diskpart, tried Powershell but everything returns an error that Access is denied.




I have tried booting in to Safe Mode, moving the pagefile over to another disk but nothing seems to work.

This is an OS drive for our Exchanage server so formatting or blowing it away in any fashion is out of the question. I am able to drill in to every folder and create files, delete files, basically do everything except expand the drive out.

These are the only errors related to the issue that I can find in the logs under, Application and Service Logs > Microsoft > Windows > StorageManagement






Is there something obvious that I am missing as to why Disk Manager is denying my access?

Disk management console view is not up-to-date

i dont know how to fix your disk management, but i can fix your partition problems...




open up Command Prompt with admin rights. (Right click, run as admin)


enter in
DISKPART
list disk

then find the Disk number for your Raid array... lets call it number 7 ( you can tell what disk is what by the total size)
type in

Select Disk 7
List Partition (will give you a list of all the partitions..)
Select Partition 1 (im assuming you only have 1 partition on Disk 7) repeat this step if you have more partitions.
ASSIGN


that should get the array up and running ready to use.


EDITED.

any problems, post back ^^


Still EDITING *Stick Out Tongue

side question, have you tried restarting the PC?

 

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that
