iPhoto hanging after moving my data to a new drive

[wickerman]

Whilst shuffling data to make space on my HD, I moved all my photos to an external drive. Now, every time I launch iPhoto it becomes unresponsive and I have to force Quit. How can I fix this? (I've tried rebooting.)

Have you tried starting iPhoto while pressing the Alt key, and then pointing it to your new Library location?

Launch iPhoto whilst holding the Option-Command keys, which will bring up the Photo Library First Aid screen.
You can run each choice, particularly after doing a relocation like you have done.
Each choice can be helpful, but Rebuild Database is likely what will help you the most.
Some choices can take a considerable amount of time if your iPhoto database is very large, so be patient.

Could you have, perhaps, moved the data to another hard drive that is not in HFS+ format? Like maybe FAT32 or NTFS or something?
