One of the hard disk partitions is missing

Recommended Posts


Am running my PC on Windows 7. It´s hard disk had Drive C plus 3 other partitions. One of the partitions has disappeared, along with all the containing data.


Any clues on how can I recuperate such missing partition?

Check if that partition exists in the "Disk Management". 

Hold the "Windows" key and press the "R" key. Run dialog box will appear. 

Now type diskmgmt.msc and press Enter. 

"Disk Management" will be opened. 

If you notice a partition without a drive letter then right-click on it --> Select 

"Change Drive Letter and Paths..." --> Click on "Add" button --> Add --> Select 

the drive letter --> Click on OK. 

Good Luck

Personally, I have never seen a hard drive partition "just disappear" without any associated activity in that area. Moreover, some partitions are actually "hidden" from view. An example is shown below where a hidden partition is not shown in disk management but is clearly there when the diskpart command is used. So, what were you doing when the partition disappeared? What was on it that needs to be recovered?
