I'm not sure why there is a requirement that your HD be formatted into NTSF to install the Oculus software. The format of the drive should have NOTHING to do with system and I'm sure since most people buying the Rift are developers of some kind (such as myself), they have a similar setup of a OS drive and a content drive formatted in ANYTHING else but NTFS as it's not a good file system. Why was this ever made a requirement?
