2TB HDD Under Windows 7 Tags: Windows 7 Disk Management Hard Drives Last response: October 18, 2011 3:40 PM in Windows 7 Share Andy5112405 October 18, 2011 1:47:20 PM Hello, I've just installed a Samsung 2TB HDD into my Windows 7 Ultimate 64 Bit system. Under Disk Management the system shows the 2TB drive with 1.82TB of available space. However, after formatting I can only use 68% of this ie 1.28TB ????

So I installed latest mobo drivers and solved the problem. | Report abuse Andy5112405 October 18, 2011 2:50:32 PM Yes its formatted NTFS. I'll try newer MOBO drivers but BIOS is seeing the drive as 2TB and Windows 7 ia also seeing it as 2TB. Its just that the useable size is only 1.26TB ?? | Report abuse Hawkeye22 Windows 7 Authority October 18, 2011 3:40:04 PM How many partitions is disk management showing on the drive?
