erm . .to be honest, i've had the same situation some months ago (SFS 1.214) due an early BT version of Amigift.
Although i've been able to restore some dirs (with SFSSalv) the most went been lost :-(
I've noticed that you are using blocks of 2048 . . .why so large?
If on those partition, you have to do with large files, so OK (ie video-audio editing or so) otherwise, a smaller blocksize, will enhanche your HD performance a lot.
