Hey all. On the off-chance that you happen to be working for a company that owns the laptop but have had the laptop ownership passed to you recently, you can just call Dell technical support and they will provide you with an Admin Password override. Once entered on the Admin Password entry page during bootup, it will reset the BIOS passwords, including the Configure Setup password. I do not know if this also works to reset the HDD password, as I was not having to deal with this issue.
Hope this helps!
