The destination disk must have enough space to store the target disk's data. In addition, all the original data on the destination disk will be deleted finally. So, you should transfer or make a backup of its important data in advance.

Part 3: How to Wipe a Hard Drive without Deleting Windows10/8/7/Vista/XP


I used this tool to erase hard drive without losing Windows.



In fact, wiping partition is a kind of overwriting which involves the process of replacing old data by new data. Once the original data are overwritten even just once, they will be generally considered to be unrecoverable. Overwriting is also the principle of "Wipe Partition" in this software. To guarantee the wiping effect, this software supplies you five wiping methods with different overwriting modes, and you will have the chance to select a proper one according to your individual requirements during the operation process.

Suppose that disk 0 is divided into two partitions (see figure below). Partition (C:) contains Windows OS, which should be reserved to guarantee the computer's normal running; partition (E:) saves some important and sensitive data, and you want to erase all data on partition (E:) from the hard disk forever.

Part 5: Other Assumptions to Erase a Hard Drive without Losing Windows 10/8/7/Vista/XP


Until now, some of you may still doubt that is it really necessary to use a third-party tool to wipe a hard drive without deleting Windows OS?

First, you may mention Windows snap-in Disk Management. However, with this manager, you are just allowed to format or delete the selected partition or volume instead of erasing all data on it. Therefore, anyone can restore these formatted or deleted data with a piece of data recovery software. This tool is unavailable to resolve your problem.

disk management delete format

Then, you may think of Diskpart command line. Of course, you can wipe all data on the whole hard disk by inputting "list disk" > "select disk (disk number)" > "clean all" in the Diskpart interface. It doesn't matter if Windows OS is not saved on that hard disk. But once the data partition and system partition are both on the selected disk, you will not be allowed to execute this Diskpart command line finally and you will see a piece of error as: "Clean is not allowed on the disk containing the current boot, system, pagefile, crashdump or hibernation volume". It is not the way you are looking for neither.

diskpart

So, it is actually inapplicable to use these two Windows snap-in tools to wipe a hard drive without removing Windows if the data partition and the system partition are on the same hard disk. Naturally, these two assumptions are invalid. You still need a third-party tool - MiniTool Partition Wizard - to help you.

Part 6: Bottom Line


All in all, don't hesitate to use MiniTool Partition Wizard when you want to wipe your hard drive but keep Windows OS for it can solve a lot of problems for you:

First, if it is necessary, you can use the "Copy Partition" and "Copy Disk" functions of MiniTool Partition Wizard to make a backup of the important data on the partition and hard disk before you wipe them;

Then the "Wipe Partition" feature of this software enables you to wipe the data partition and reserve the system solely as you want to.

In addition, due to the target partition is shown as "unformatted", you still need to utilize its "Format Partition" and "Change Drive Letter" functions to format the partition and add a partition letter to make it to be displayed on the computer normally.

Indeed, MiniTool Partition Wizard achieves all operations in one tool, breaks many limitations in Disk Management and Diskpart, and owns more partition functions. It is truly a powerful program in the field of partition management.
