Anime Expo game demos - hands on and what was there

Not to mention criminal charges of theft.

 

I LOLd reading this.
FYI, a surge cannot "erase" your HDD, if you are writing to it though (depending on your file system) you might lose access to it if the header is not updated, because the filesystem cannot make out the location of data. If you are lucky, you may lose just the farthest data on the platter. I guess the Xbone devkit uses some kind of integrity protection that went bonkers when the power shut, so they had to rebuild the partition table.
I once overwrote a NTFS HDD's partition table and stuff. You can recover the data by using a forensics tool like WinHex to replace the first sector with another NTFS drive's one and then recover data manually by copying it to another location. It's a pain in the ass but it works fine.
