Encryption of Time Machine backup went wrong

Encryption of Time Machine backup went wrong

I use an (Mac OS - journaled formatted) external Lacie harddrive to back
up my Macbook Air via Time Machine (The external harddrive also contain
other data besides my backups). The OS is Mountain Lion, and I have chosen
to encrypt my backups in the settings from the Time Machine preferences.
The backup initiates automatically when the two devices are connected, and
I had to interrupt it because I needed to leave, along with the Mac. I did
so, by cancelling the backup, waiting a couple of seconds, but seeing as
the backup symbol kept spinning, I pulled the cable and hurried of with
the machine. Now the external harddrive will not activate when connected.
It's visible in Disk Utility, but cannot be activated. When you unplug the
cable (thereby disconnecting the external harddrive) it suddenly asks for
the password to the external drive. I gather that something went wrong
during the cancelling of the backup, where it was encrypting. Can I
somehow lift this encryption-gone-wild and get access to my data again?
Thank you very much
