Moving JPG from Window XP to new MacBook Pro
I have a new MacBook Pro and I am in the process of moving all of my data / picutures from my PC (Windows XP) to my Mac. I have used a Seagate external hard drive that I used to keep my PC backed up to load my files on my new Mac. I have pictures from 2001 to current on the hard drive. All of the picures that I have taken from my iPhone loaded just fine, however MOST of the pictures will not open in either Preview, or iPhoto. The pictures that do load come up half grayed out and or missing. The error message that is displayed is "File Cannot be Opened. It may be damaged or use a file format that preview doesnt recognize". Ive seen several post about running the disk utility to repair damaged files. Disk utility wont work on the Seagate hard drive (not sure why). Not sure what is going on. The pictures open just fine on my PC. What is the easiest way to get my family pcitures loaded on my Mac and viewable / usable in iPhoto?
Please help.... Thanks
MacBook Pro, OS X Mountain Lion (10.8.2), Iphoto '11 version 9.4.2
