Safe and Easy Ways to Show Hidden Hard Disk Partitions
There Are 3 Types of Hidden Partitions
Partitions Hidden via Removing Drive Letter
Users can intentionally hide a partition by removing its letter in Disk Management or third party program.
In Disk Management:
Right click the partition you want to hide, choose Change Drive Letter and Paths, and tap Remove and then OK.
In third party program (take MiniTool Partition Wizard Free Edition for example):
Select the partition you want to hide, choose Change Drive Letter feature from the left side, then select None from the drop-down list of New Drive Letter, tap on "OK", and click "Apply" to perform the change.
In addition, Windows will hide the system reserved partition (Legacy BIOS) or EFI system partition (UEFI) by not assigning it a letter.
Partitions Hidden by Third Party Program
Using third party program you can hide a partition easily, and this kind of hidden partitions are quite different from those simply without drive letter, because it hides partition via modifying partition type ID. You can use MiniTool Partition Wizard to hide a partition.
If you have installed Partition Wizard, now launch it to get its main interface:
Then, select the partition you want to hide and choose "Hide Partition" feature from the left side.
Now we can see status of the selected partition becomes Hidden. At this time, as long as you click "Apply" button, this change will be applied to your computer.
Partitions Hidden by Manufacturer
In Disk Management or third party partitioning programs, you may see some wizard partitions, such as Recovery Partition and OEM Partition:
These partitions are hidden by manufacturers and related to system restore and factory reset. Generally, we are unable to access them since they are not allocated with letter, and Disk Management also does not give an option to give them letters.
Well, is it possible to unhide all these 3 kinds of hidden partitions? Of course, it's possible.
How to Show Hidden Hard Disk Partition
For partitions hidden via different technologies, we need to use different methods.
Tip: all our tests are made in Windows 7, but operations in other Windows operating systems should be the same or similar.
Unhide Partitions Simply without Drive Letter
Please type diskmgmt.msc in Search box and run this utility as administrator to get the interface below:
Then, right click the hidden partition, choose Change Drive Letter and Paths, and click Add to give a letter for this partition.
Tip: you'd better add the original letter for this partition, otherwise programs relying on drive letter might not work correctly.

Then, launch the program to get its main window:
Next, select the hidden partition and choose "Unhide Partition" feature from the left side.

Show Partitions Hidden by Manufacturer
We are going to introduce 2 ways to unhide this kind of partitions.
1. Show Manufacturer Hidden Partitions in Partition Wizard
Please download and install the program to your computer. Of course, if you have installed it, just ignore this step.
Then, launch the program to get its main interface.
Then, please select the partition you want to view and choose "Explore Partition" feature from the left side. After that, all contents in the selected partition will be shown clearly.
No commands are required, and no information is modified. That's an easy and safe way to show hidden partitions.
Then, let's see the second way if you are unwilling to use third party program.
2. Unhide Manufacturer Hidden Partitions in Diskpart
For ordinary users, it might be difficult to unhide this kind of partitions, since it should be done in Diskpart and requires complex commands.
Show Recovery Partition
Firstly, please type diskmgmt.msc in Search box to open Disk Management, and then focus on disk number (the disk holding recovery partition) and its partitions.
Then, type diskpart in Search box and run it as administrator.
After diskpart is launched, please type the following commands, and each type ends with pressing on Enter key:
Select disk N
(N is the number of the disk holding recovery partition)
Select partition N
(now N is the number of the recovery partition)
(remember the type value of the partition, which is good if something goes wrong)
Set id = 07 override
Then, you can check whether your recovery partition is accessible in either Windows Explorer or Disk Management.
Show OEM Partition in Diskpart
Actually, we can unhide OEM partition like unhiding recovery partition in Diskpart, but there are many cases reporting that doing this makes Windows unbootable. So, we do not recommend this method. Just show these partitions in MiniTool Partition Wizard.
Actually, if you have created a backup for your system, there is no need to keep manufacturer hidden partitions. And you can delete them to release free space. View the post Solutions to Deleting Drive C, EFI System Volume, Recovery/OEM Volume to get steps to delete such a kind of partition, and then refer to the post Extend Partition to add the released space to other partitions.
