I have a company laptop, whose one and only hard drive was encrypted with Bitlocker. I have tendered my resignation with that company and they immediately used the remote security policy to lockout my logon account. I would prefer to wipe the drive myself before returning the laptop to my employers, just because I'm paranoid. I suppose I could take the drive out and slave it to my personal PC to reformat it, but that would require buying a cable to do so and I'd rather not if there's a way to do it from the laptop in question.
The facts:
- I don't care about accessing anything on the disk; Just want to wipe it all
- When I changed any boot option (such as allowing the CD to boot before the HDD, to use Boot-and-Nuke), the TPM locked me out.
- I can get to the Win 7 prompt but have no local users with which to login
- Disabling the TPM tells me Windows can't be started (instead of showing me a garbage disk as I expected)
- I thought using the "Clear TPM keys" option in the Dell BIOS would trash the data (making it unusable and wipe-able), but I can still boot to Win7 after doing so.
- I reformatted and gave away the external drive that had what I believe to be the only BitLocker recovery key on it.
I understand that Bitlocker is totally working as intended by not allowing me to both boot the drive and also get a command prompt or the like, but I'm looking for a way to get to a command prompt (or boot from CD) WITHOUT booting the HDD so that I can kill all the data on it. Any ideas? Thanks!
FOR THOSE CONCERNED: I'm not sure what repressive employers some of you have worked for, but my company trusts me enough to wipe a drive before sending my laptop through the mail. It is in fact company policy to do so because any data related to a past project that may be on the drive is subject to nondisclosure and sometimes security-clearance restrictions.
