How to: Use Diskpart to Clean Partition Only
Want to clean one partition only using Diskpart and keep other partitions intact on the disk? This post illustrates different solutions to clean single partition only.
“I have an external hard drive and it has two partitions (E and F). I know that I can use “clean or “clean all” command in Diskpart to erase all data on the external hard drive. But what I want to do is clean partition E only and keep partition F intact. How can I achieve this goal using Diskpart?
It’s necessary to realize the difference between “clean” and “clean all” commands. Both of them will delete all partitions on the selected disk and leave it unallocated. However, “clean” command only marks the data as deleted and the data can be retrieved easily via data recovery software; “clean all” command write zeros to the disk, which makes it’s more difficult to recover erased data.
If you want to clean a partition without writing zeros, you can delete the partition only via Diskpart by following those steps：
Step 1. Press Windows + R, input “diskpart” and press Enter.
Step 2. In Diskpart interface, run the following commands in order:
▪ list disk（all the disks on your PC will be listed）
▪ select disk n（“n” is the disk number of the disk that contains the partition you need to clean）
▪ list partition（all partitions on the selected disk will be displayed）
▪ select partition m（“m” is the partition number that you want to delete.）
▪ delete partition
Step 3. After you see Diskpart successfully deleted the selected partition, type "exit", and hit Enter to close this program.
