Windows 10: hard disk with two partitions and with one unidentified space

Dear sirs,

hard disk has three volumes , two are recognized as assigned partitions , third one is unidentified space ,and not possible to access and select any option. There is an empy space only with a question mark. Is there any possibility to correct and have unallocated space and therefore partitoning?

thank for the help.

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

 

Hard disk partition not showing up.

Hi Muhammad,



Thank you for writing to Microsoft Community Forums.



This can happen if the Hard-disk drivers are not up-to date. I would suggest you to update the hard disk drivers first. To update the drivers, please follow the steps mentioned below:

1. Open Device manager.
   
2. Then Expand “Disk drives”.
   
3. Then Right click on the Hard-disk listed under this category.
   
4. Then click on Update drivers.
   
5. Alternatively you can also try to update the drivers from manufacturer’s website.
   

Once the hard-disk drivers are updated, you will need to allocate the last partition (it is not allocated according to the screenshot) and you will be able to view the partition.



Also note that sometimes the hard disk partitions/drives might be hidden in This PC or My Computer window due to a Registry key. If a DWORD with the name NoViewOnDrive or NoDrives is present under following key in Registry Editor:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer

Delete the DWORD and your drives will become visible in My Computer window.



Hope this helps.

 

Hard disk space

The first and most obvious reason you don’t have access to all your hard drive space is that there’s a significant piece of software installed on it already: your operating system. Unless you specifically selected a “no OS” model, it will come pre-installed
with something.

Another place your hard drive space might have gone is to a manufacturer-created disk partitions. In years past, a new computer commonly came with one (or a whole book full of) CDs containing software, including a recovery disk. In the event of a total meltdown
of your machine, you could boot from this drive and restore your computer to an right-out-of-the-box state.

Other possible reasons including hidden partitions, unpartitioned hard disk space, system protection takes up much space and many others. check out

this tutorial to see how to solve it step by step.

Hope it is helpful.
