A Hibernation Partition can be seen in Windows File Explorer and Disk Management in some laptops. Usually, the partition size varies from 4GB to 8GB as a separated partition on a hard disk especially SSD, marked as Healthy. Hibernation is a power-saving state which saves the snap shot data in Windows. Then, what a Hibernation Partition is and what the difference between hibernation files and this partition is.
The Hibernation Partition is a separate partition that contains hibernation file used by Intel Rapid Start Technology (IRST). It is a special partition that is used exclusively by IRST, depending on the PC’s BIOS or UEFI, so not all laptops have Hibernation Partition. You can find this partition on HP, Dell, Toshiba, Lenovo, etc. PCs.
The Hibernation Partition is always the same size as the installed memory because it writes the contents of memory to the disk partition to hibernate. It puts your work and settings in memory and draws a small amount of power while sleep. That method uses the least amount of power among all power-saving states in Windows.
Generally speaking, the Hibernation Partition and the single hibernation file are created by different enterprises. The former is created by Intel and the later is Windows. In addition, Hibernation Partition exists on some certain laptops that used by IRST particularly. However, Windows hiberfil.sys can be found on almost all kinds of laptops.
The biggest differences between them are the location and mobility. As mentioned, the Hibernation Partition is a separated partition that locates on SSD and can be located anywhere on any SSD in the system. However, the Windows hibernation file (c:\hiberfil.sys) must be readable by the bootloader, and be stored in the root of the primary system partition where it can be read by the miniature file system driver built into the critical boot files. And it cannot be relocated.
Although they have such differences, the intention of them is the same: save PC state so that you can back to work quickly.
What is the necessary of removing hibernation partition in Windows 7? After all, it is an effective way of saving power. In fact, there are two main reasons account for deleting hibernation files.
Full use disk space. In some cases, the laptop system disk has a small disk like 128GB capacity. Even if the Hibernation Partition takes up only 4GB or 8GB, it is a big amount of space for that small disk. Therefore, some users want to delete Hibernation Partition on SSD to utilize that space. Also, if a user has no need for computer hibernation, he would delete that partition regardless of the disk capacity.
Change Hibernation Partition size. The original Hibernation Partition size is decided by then installed RAM. However, if you add an extra RAM stick, the partition size needs to be extended. Under that circumstance, delete the old Hibernation Partition and then create a new one with new size is the most acceptable solution.
You may have other reasons when talking about removing Hibernation Partition. However, it is more important to learn how to delete the partition with ease.
