1.1956 years, IBM's IBM RAMAC is the prototype of a modern hard disk, it is equivalent to two refrigerator volume, but its storage capacity of only 5MB. 1973 IBM 3340 came out, it has "Winchest" this nickname, from his two 30MB storage unit, just the famous "Winchest rifle" caliber and the amount of ammunition. At this point, the basic structure of the hard disk is established.

Therefore, to use a 3TB hard drive must be a UEFI bios and GPT partition.
In the operating system, the 64-bit WIN7 and Vista,linux and Mac OS X1.6 support GPT booting, so you have to install 64-bit WIN7 or Vista, or Linux and
