Yosemite First Install Attempt

My first attempt at installing Yosemite failed in an inability to complete expanding a file for installation. I was upgrading from Mavericks on a USB 3.0 drive. It rendered the drive un-bootable (I do have backups). Crashed at about 18 minutes remaining. Could the drive or drive controller overheated? It’s in a small aluminum snap together case. Here’s a pic of what it did to the drive:

The second attempt worked just fine except for App Store is trying it’s best to update stuff that it already has. I installed to the internal spinner drive. Stuck here:
