Just a short note on those of you who use this tool on an infrequent basis. Even though the tool still states you need a flash drive with 4GB of free space, the latest download has now ballooned to 4.42GB and will not fit on a 4GB flash. I've been using 6 or 8GB flash drives and it works fine. If the flash drive is too small, the installation will error out with an odd code and not really say why it failed to finish. Compounding the situation, as with some HDD manufacturers, they are still stating the size of the flash drive in decimal bytes(1MB=1,000,000bytes) not in digital world bytes(1MB=1,048,576bytes).
