Windows 7 HP XW4400 Workstation: Lost W7 Password.

[Fenton]

Hi.

I created a new Password and added it to a Disk. I forgot the Password, but for an unknown reason, the Disk does not work. Any advice much appreciated.
Thank you.

If you mean a Windows account password you can reset them.

For local accounts you can use the NT Offline password editor

If you're using a email address as your login

If you mean you encrypted the hard drive and forgot that password you'll need to reformat the drive as brute forcing those passwords are close to impossible.
