1GB Chihiro images crash fatxfs or has blank root directory

[GXTX]

Attempting to load a 1GB Chihiro FATX partition crashes the driver.

Using the size as described in the example we end up crashing the driver.

--size=0x01f400000

Using a 'correct' size as calcuated by JayFoxRox's Chihiro-Tools project we end up being able to mount the image - however the root directory is empty.

--size=0x3B7D9000

Log with --size=0x01f400000 is too long to post, see: https://pastebin.com/Vy4ykv1u

Log below is from --size=0x3B7D9000

A 512MB FATX partition is able to mount, read, and write using the example --size=0x01f400000.
