Caution for installation of 3TB in full 3 TB requires that the driver INTEL RST (AHCI / RAID) PC Windows 7/8 is greater than version 10.1 (see this in Device management / IDE ATA / ATAPI corresponding line): If this is not the case you must update it by taking the latest Intel RST driver from your motherboard (this driver effectively replaces the Windows 8.7 Disk Management ACPI / RAID and it possesses General Install a file).
Then:
Once the mounted disk with Tools Administration / Management Windows discs 7/8, initialize the Seagate 3 TO in GPT (MANDATORY) - right click on it - then do a quick format.
AND it roll my chicken!
No need to use the Seagate Dicskwizard software that also well control than Intel RST driver version is correct.
