Ok, If I ask again what happens when you convert to a PSD that will be 3 times, maybe 3 is my lucky number.
You haven't given specifics on what you did and how you did it.
You haven't said by what process you determined that your Raw and JPG file are OK.
No more questions, I'll just tell you what I would do if I were you.
For starters I'd run Chkdsk /F if you have a PC then ........
Copy the Raw files from the card to a new folder on the HDD.
Open the new folder in Bridge.
DO NOT assume if the images look fine in Bridge the RAW files are OK, you're looking a JPG thumbnails not the RAW files.
Click on a RAW file in Bridge.
This will open it in ACR.
Now examine the image for problems.
No problems, open it in PS and save it as a TIF.
Close the TIF and reopen it, still OK?
Do this with 8, 10, 12 images.
What happened?
