Reset Your SSD With Windows DiskPart

Labels (2)

These steps show you how to use the Windows DiskPart, Clean command to quickly delete any partitions on the SSD and reset it to an uninitialized state.


Please note, these steps in themselves do not actually remove the data from the cells on the SSD it merely removes any partitions that were created, meaning you no longer can access the data and the drive appears as uninitialized. This is ideal if you have set up an incorrect partition or selected GPT instead of MBR or any other situation where you need to reset the drive to appear as it did when you first received it.


Open the Command Prompt as an Administrator


To run the DiskPart command, you need to open a command prompt as an Administrator.

Steps to check disk number in Disk Management

  • Type Computer Management into search and open the Computer Management utility
  • Select Disk Management near the bottom of the left hand menu
  • A list of all attached disks is loaded and listed as Disk 0, Disk 1 etc.
  • These numbers correspond to the numbers in the list disk above
  • It should be easy to tell from that list which is the main drive and which is the drive you wish to reset

- Type select disk # and hit Enter (where # is the disk number you want to reset)

Troubleshooting


Permissions
If you get any errors about permissions when trying to run DiskPart, make sure you have Administrator privileges on that computer and that the command prompt is opened as an administrator. It is easy to tell as it tells you in the title bar and defaults to the path C:\Windows\system32>


Writing to disk
If you get a message telling you that the disk cannot be written to or is not accessible, double check the connection of your SSD. For example if you are using an external caddy, try using an alternative connection like a USB to SATA cable.
