Recently my HDD was encrypted by a ransomware attack (I have no idea which encryption method has been used) and as a result I cannot access the contents of my HDD (see how Disk 1 seems in the first screenshot).
Now I need to completely format it to be able to use it again, however, when I try to format this disk via Disk Management tool on Windows, I cannot do it because of this and get an error.
Is there any way to wipe my HDD on Windows?
If not, what are the other options?
The following are the screenshots to give more information about my problem:
