Can't view photo library from My Passport in iPhoto library

Have never had issues opening external drive photo library into Mac iPhoto Library until today. When selecting Switch to Library > Other Library > iPhoto LIbrary from My Passport for Mac > Open. I just get a running log of unreadable files. Any suggestions? I’ve tried Switch to Library and Import LIbrary and I get nothing.
Thank you!

Hi there,

I have not tried this, lets see if another user can share some information or tps on this matter, also you can try to eject the drive and then re connect it to see if this can help you out.
