How to wipe unbootable hard drive?
Last week, pc advisor user asked a question about how to wipe an unbootable hard drive which had Windows 10 installed. Actually there're many plans to wipe data clean off a hard drive especially when the owner decide to make it as a secondary hard drive instead of physically destroy it which unexpectedly to be the best answer. Here's the question:
I've got a 1tb hard drive that has got like 600gb of data on and Windows 10. The hard drive is no longer bootable and I'm not sure how to retrieve the data and I don't want to pay someone else to do it because I have no money to do that I and have private things on it which I wouldn't want to share. The data isn't that important but I do want to completely wipe everything and use it a secondary HDD for my pc. Does anyone know how to remove everything even the os and use it.
Just like another user just mentioned that the unbootable hard drive doesn't mean it's dead. It might be SATA port loose, the disk is disabled in BIOS setting or it really has many bad sectors. We can dismantle the computer and check if the hard drive is not well connected or disabled in BIOS. We can then use another computer to test if the hard drive has bad sectors with some disk scanner software.
Although the thread starter had choose the physically destroy as the best answer, other user may not agree to this when the hard drive they installed are rented from Server providers. So here's the alternative solution.
Erase Entire Disk
To wipe the unbootable hard drive clean with software we can do as follow after we connected it to another bootable computer:
1. Download the data sanitization program ByebyeData Eraser, install and Run it as administrator.
2. Open Windows Explorer (Press Windows button + E to open it with shortcut in Windows 7, or just double click This PC in Windows 10) and check if all the partitions of the unbootable drive are listed here. Or Run Disk management to see the disk partitions for more information. (uninitialized, unformatted or unallocated space).
If you can see all the partitions in Windows Explorer, make a backup for the documents means to you. And we can proceed.
3. Click the Entire disk tab and all the disks connected to the computer are listed in the right part of the main window, then select the unbootable disk.
4. Choose a wiping method for the disk. Since it’s about to be your secondary hard drive, the zero-filling method is the best option, it takes shorter time than multiple passes overwriting and it’s enough for data cleaning.
5. Click Erase Now and confirm the message, then ByebyeData Eraser will start to overwrite the hard drive.
Using software to wipe hard drive is the best option to keep the hard drive and say bye-bye to data, while physically destroy a hard drive is more helpful when the disk is out of its service or data on it is so important that you can take a slim chance of leakage. I think this scheme maybe not the best answer, but it is more acceptable for most users.
