One can easily spot the problem in the picture below: By the time a user is ready to upgrade to 3TB drives I would generally recommend that it is also a good opportunity to upgrade to a 64-bit version of Windows as hardware is starting to advance well beyond what the older Windows XP generation operating system can handle. To test the problem I am going to use a Hitachi 5K3000 Coolspin 3TB hard drive with an Intel H67 motherboard’s onboard 6.0gbps controller in AHCI mode, alongside Windows 7 Professional SP1 64-bit. RST 2.8GB and Disk Management 746GB – 64-bit OS The Problem


Test Configurationįor this guide I am using my standard hard drive test platform based on an Intel H67 motherboard. As a result, I decided to make a guide so other users can easily fix the problem. I myself fell victim to not following best-practice and seeing this issue manifest itself recently when I was benchmarking a new drive. I receive questions about why this happens on Hitachi, Western Digital, Seagate, and Samsung drives on a regular basis so I think this is a fairly common issue. Many users have been finding themselves with brand new Sandy Bridge motherboards and the hard drive industry’s now affordable 3TB drives only to see that the new drive only has 746GB available in even 64-bit Windows. I am able to access the data on the drive just fine it's mostly videos & there are a few other small things.Intel RST 2.8GB and Disk Management 746GB I looked around online and didn't find anyone with this specific problem, though I did have trouble refining a precise enough search for this issue (most of the results being returned were for the "opposite" problem, wherein Windows would over-represent the used space rather than the free space for various reasons) It's odd that Windows is apparently aware that there is ~7gb of data on the drive (as you can see that the Used Space is being reported correctly), yet it incorrectly shows the drive as completely free Hi all - I have an internal HDD with ~7gb of used space, but Windows Explorer (and 'Settings > Local Storage') both report the drive as being totally free (see screenshot below)
