Moved iPhoto library to an external drive now really slow
My library is now on an external 1T connected by fire 800, it responds extremly slow and shuts down at times. Can not find my photos to use for desk top picture or screen save like I did before.
I have a 2008 imac, with 6g ram, 320hd with over 212g free. I have over 250g pictures, that is why I moved then to the external drive.
Iphoto 11 (9.4.3) on Lion 10.7.5
Do I have to live with this? How to do it better? Do I just need to upgrade my IHD to fit all the photos?
iMac, Mac OS X (10.7.5)
