Whonix - formatting second disk

Hello T
he problem concerns logging into the Windows system.
I have two disks on my computer; on one disk the Whoonix system, on the other Windows. The Windows system has ‘crashed’; I can’t log into my account in any way because after reinstalling, restoring data, etc. my password doesn’t work. I don’t know why…
Can I somehow get to the disk with Windows from the Whonix system?
Can I format it completely from Whonix? If so, how?

I would be grateful for suggestions.
