Unable to view images!

[Fotografer]

At my photoshoot yesterdayI ended up with half of my photos on one of my SD cards not being readable by photoshop CS4 or in camera (it was showing a yellow question mark). I viewed the meta data with exif and evertything looks fine. I also tried ZAR recovery and Stellar Phoenix with no luck. The file sizes are right and the meta data is right but photoshop continues to say it is an unreadable format.</p>
