Q: Why isn't the system disk at drive C after the OS installation?(DigiDice)
A: DiGiDice is integrated with a card reader, if user used a new hard disk without partition to install the OS, OS will keep the card reader as removable disks in front of the hard disk so the drive letter of the hard disk will not be at C. In order to deal with this, please partition the hard disk first or unplug the card reader line before the OS installation.
