I purchased a refurbished iMac 27" Late 2013 running Yosemite version 10.10.2. I had an old Macbook Pro and was using a WD external drive for my time machine. I backed up the Macbook Pro and then detached the hard drive and attached it to the new iMac and started migration assistant. During transfer on the iMac it will get to 2 minutes left and hang for days. Here is the kicker while doing that I wiped the Macbook Pro hard drive. I can see that there is data on the WD external drive ((mostly movies, pictures and music) really all I need off of it). What is the best possible way to export the data off of the WD external drive?
MacBook Pro 2.5 GHz, Mac OS X (10.5.2), 2 GB 667 MHz DDR2 SDRAM
