My WD Passport disk went down, the complete file structure is corrupt and there is a h/w issue as well. Though I backed it all up on my timecapsule but not so. Forgot to set it up for external disks.
Thanks to DiskWarrior I manage to temporarily map the drive and directories again.
Thanks to FileJuice I managed to retrieve 2500 images from my damages Aperture library..
Total cost for the s/w is less than 100USD, well worth the money!
