2 years ago I bought a “My Passport”. I took several hundred photos while on vacation and transferred them daily from my digital photo card onto my passport for safe keeping. I verified they were on the my passport prior to deleting them off my card. I now want to transfer these photo to my new computer. I plugged in the my passport to my new computer and am being asked if I want to format the disk. Something must be wrong. Where are my photos? I did not click OK. What is the issue and how do I fix it? Any ideas?
