So, I screwed up. I brought my external HDD to a VS2008 Hands-on Lab thinking it would be helpful...and it was!

The Lab was overbooked, and there weren't enough Microsoft supplied HDDs to go around. So, in my infinite wisdom, I said, that's ok, let's just copy everything over to my external HDD, and the other guy can have the MS supplied one. 30 minutes later, the copy fails. The virtual image won't transfer because, apparently, it can't fit it's measly 14Gb into the 210Gb of free space on my HDD. Well, it turns out that I was a little too excited when I got my external HDD, and I started using it without checking the format. Sure enough, the external HDD is formatted as FAT32 rather than NTFS. Who knew?

Luckily, the guy running the Lab, Jeff Brand, figured it out almost immediately. More importantly, he was kind enough to transfer all the files off the external HDD, format it as NTFS for me, and copy everything back on. Thanks, Microsoft, for keeping from being FAT.
