> Due to 32bit integers in both the trafficersever code and the ioctl used to
> determine raw disk size, the number of sectors reported to the cache storage
> system is bound to 0-0xFFFFFFFF. If a disk has 512 byte sectors and is
> larger than 2TB it will report (num_sectors % 0xFFFFFFFF) * 512 bytes
> avaliable.
