iphoto library access issues

Please can someone help me with the following.

Overall objective remove all content on macbook pro (running crazy slow)

A) have itunes and iphoto libraries available for access by my mac desktop

B) have an independant set of original photos (not mac'ified)

Fyi approx 9500 photos

Actions taken so far...

Backed up macbook pro to time capsule

Bought wd my passport fpr mac -guy in shop formattex so can use on windows and mac machines

Exported photos in original file format to a wd my passport for mac - tested and can access from both a mac and non mac machine...successful

Copied itunes library to wd my passport for mac - tested can access on mac desktop..successful

Problem

Dont seem to be able to copy iphotos library to wd my passport for mac

Copied iphotos library to time capsule but when try and access using mac desktop nothing happens...in quit view iphoto states not responding

Not sure what the issues are with what im trying to do?

Do i need another wd my passport for mac formatted just for mac on which to run iphoto library?

Can i run iphoto library on wd my passport for mac which has been formatted for both windows and mac?

Why can i access itunes library off time capsule copy but not iphoto library?

All help gratefully receivef
