IMPORTANT INFO:
1GB = 1,000,000,000 bytes. 1TB =
1,000,000,000,000 bytes. Once formatted, the actual available
storage capacity varies depending on operating environment (typi-
cally 10-15% less). For example, if the total disk size is 500 GB, the
formatted capacity should be approximately 465 GB. If the used
capacity is 145 GB, remaining capacity will be 320 GB.
