Windows 10: Disk D: Partition Gone.

After our hardware maintenance, the Disk D: partition was gone. I tried rescanning from Disk Management and System restore but It wasn't able to fix it.

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

 

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?

 

Disk Management not responding in Windows 11 - not able to delete 'Basic Data Partition' D:

I suggest you use diskpart as follows. Press the Windows Logo key+X and choose Command Prompt (Admin) or Powershell (Admin) equivalent command. Type these commands and press Enter after each one. The capitals are for clarity only, but note the spaces in the commands.

DISKPART and press Enter

LIST DISK and press Enter

SELECT DISK n and press Enter (n corresponds to the disk you want to delete from)

LIST PARTITION

SELECT PARTITION n and press Enter (n corresponds to the partition to be deleted)

DELETE PARTITION OVERRIDE and press Enter
