Unlock when OS is down

I protect MyBook by password and use, among others, to store a disaster recovery image of my system.

Unlocking, however, as far as I know, is possible via its own software, in turn, via the OS only.

When my Windows collapsed the recovery bootable CD couldn’t get to the stored image. I had to reinstall Windows (a blank copy, of course), then reinstall WD’s software, then remove the password. After all this only could I start the recovery at last.

A direct way to unlock, e.g. by a bootable CD, would be helpful very much.
