> 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.
