1.  One Gigabyte (1 GB) means 10

9

 = 1,000,000,000 bytes using powers of 10. A computer 

operating system, however, reports storage capacity using powers of 2 for the definition 
of 1 GB = 2

30

 = 1,073,741,824 bytes, and therefore shows less storage capacity. Avail-

able storage capacity will also be less if the computer includes one or more pre-installed 
operating systems, pre-installed software applications, or media content. Actual format-
ted capacity may vary. 

2.  RoHS Compatible: This product is compatible with European Union Directive 2002/95/

EC. Restriction of the use of certain hazardous substances in electrical and electronic 
equipment (RoHS), which restricts use of lead, cadmium, mercury, hexavalent chro-
mium, PBB, and PBDE.

3.  Free of brominated flame retardants (BFR) and polyvinyl chloride (PVC);  

hazardous halogens, antimony trioxide and red phosphorous also eliminated from all 
components in the hard drive.

4.  Buffer space available to the user. 
5.  Energy consumption efficiency is calculated based on power consumption divided by 

formatted capacity, as defined by Japanese law.
