how to wipe clean a previously used SSD?

[davide256]

have you tried connecting the drive to your PC and then using  "Windows Administrative Tools > Computer Management > Storage > Disk Management"

to delete the partitions on the drive? While you wont see an ext4 or linux boot partition assigned a drive letter in Windows file manager, Disk Management

should allow you to see/delete the partitions on the drive.

 

That should be all you need if the problem is removing a boot partition to allow disk reuse
