If you want to figure out whether to choose DiskPart Clean or Clean all command to wipe an SSD or HDD, you can read this article to choose. Also, an easy alternative is offered here.
Both of the DiskPart Clean and Clean all commands can help to wipe or clear data on a disk. But do you actually know the differences between the two command lines? If not, well, you can have a clear understanding from the listed points.
☎ Data wiping principle
The “Clean” command in DiskPart deletes any partitions and data on the hard disk, simply marks the data on the disk as deleted and does not zero out the disk. The “Clean all” command does the same thing as the Clean command above, but it also specifies that each sector on the drive is zeroed (secure erased), completely erasing all data on the disk.
☎ Data recovery
The data deleted by running "Clean" command can be recovered by special data recovery software. Is DiskPart Clean all recoverable? Deleted data using the "Clean all" command cannot be recovered by normal recovery tools.
☎ Data wiping time
“Clean” takes a short time to complete the data deletion process while "Clean all" takes more time about an hour per 320 GB to finish running.
☎ How to choose
If you are in need to delete the hard drive data quickly or resetting file formats while leaving most of the data recoverable, you can choose "Clean" command. To wipe the disks to reset disk to factory settings, remove any malware or bad sectors, you can choose "Clean all" command.
Moving on, you can learn the detailed steps to execute the DiskPart clean command to delete data on a hard drive, SSD or HDD.
