OMG! Think I did something stupid with dmcrypt

[Andrew Henry <adhenry@bredband.net>]

help.

I have debian lenny on a server with full disk encryption (the guided
partitioning option) and an external usb WD Mybook that is also
encrypted with dmcrypt/LUKS.

I just formatted the server to install and try out CentOS.  Then I went
to the Ubuntu Wiki to see how I can access the USB drive on another
computer, and I started reading about keys etc etc.  Have I just
overwritten my key to the usb drive whilst formatting the server?

I thought that HAL and Gnome had the ability to auto detect encrypted
devices and prompt for passphrase??  I thought all I needed was the
passphrase to be able to access the usb drive on another computer?

Please tell me ive not just lost all my data!
