    Installing Windows 10 Pro X64 on 3TB Hard Drive


    I recently purchased a internal 3.5 inch SATA Seagate 3TB Hard Drive from Amazon as it caught my eye because it was on sale. I'm trying to install Windows 10 64 bit, and my problem is that my desktop, a Dell OptiPlex 3010, is only seeing 2.7 TB (2,794GB under DiskPart) of the new drive, instead of all 3TB or something close like 2.9TB. The BIOS is seeing the entire 3.0 TB. That's several hundred gigabytes the OS is not seeing. I've done a lot of Google searches, and most are the steps I've tried with no success. I've changed the boot mode from Legacy, to UFEI and disabled secure boot in the BIOS, and I have done a BIOS update. I used Rufus to create a UFEI GPT bootable Windows 10 flash drive from the ISO. I know that I may not need a massive 3TB boot partition, but it would be nice to squeeze what I can out. My ultimate goal for this machine is to be a media center, hence the big hard drive.

    Internally, computers do not represent either hard disk drive or memory capacity in powers of 1,024, but reporting it in this manner is a convention. The Microsoft Windows family of operating systems uses the binary convention when reporting storage capacity, so an HDD offered by its manufacturer as a 1 TB drive is reported by these operating systems as a 931 GB HDD.

    Several hundred gigabytes missing at least 250GB? I know you won't the full 3,000GB. For example I have a 120GB SSD in my laptop, and Windows is showing 118GB, just a few gigs, not hundreds.

    Then your beef is with the hard drive manufacturer for labeling it as a 3TB hard drive when only 2.7TB are usable - not Microsoft or Windows 10. Windows 10/Microsoft can't use what isn't there on the disk.

    One part - the hard drive and computer manufacturers falsely claim that there are 1000 bytes in a kilobyte, 1000 kilobytes in a megabyte, 1000 megabytes in a gigabyte, and 1000 gigabytes in a terabyte. The truth is, the real numbers in binary that the computer uses is 1024.

    1000/1024 = .9766 X .9766 X .9766 X .9766 = .9095 x 3TB = 2.728 TB
