Actually, it is not cleaning the disk, it just removes the reference, and it is really easy for data recover software to have them back. So diskpart command line is a quick way to delete everything on the disk, but the improper way to secure dat. and I think that's why Howtogeek.com would like to quote the "clean" word.
How to "Clean" a Flash Drive, SD Card, or Internal Drive to Fix Partition and Capacity Problems?
Diskpart command lines to clean disks, flash drives, SD card, both internal and external hard drives' steps are:
- Run CMD as administrator and type diskpart; press enter; now you're in diskpart command line tools.
- Type: list disk > select disk # > clean. And you'll see the prompt saying: Diskpart succeeded in cleaning the disk.
That's OK for reinitializing disks and creating partitions in Disk management, but half OK if you want to clean the disk, I mean real clean not the command clean. Real clean means to erase the hard drive and make it back to factory status or as clean as new hard drives. Neither diskpart command tool nor Windows Disk management is able to erase hard drives, but if you're using ByebyeData Eraser you can do as follow to clean the hard drive:
- Click Erase Disks in the listed function tab and choose Disk 1, the same disk you selected in diskpart.
- Choose a cleaning standard and click Erase Now.
- Confirm the erasure step by typing the keywords and you can say bye-bye to the disk data.
