Saving your corrupt PSD files (and job?)
Photoshop file (PSD) Extract/Recovery tool

Friendly quote:
This plugin lets you grab image layers from any PSD/PSB file. It's faster than opening the whole PSD in Photoshop, if you just want a layer. Most importantly, it can usually recover image layers from corrupted PSD files that Photoshop won't even open (if Photoshop opens with damage, this plugin recovers a more intact image).
This plugin is opensource (under GPL), free (gratis) though donations are welcome if it saves your day/sanity/job ;)
Advanced users are welcome to contribute improvements
