Windows 10: HDD Partition Not Showing Up

Yesterday, I changed my motherboard and CPU and upgrade to Windows 10. Fortunately, that all went over without a hitch.


Today, I installed my 4 TB HDD, my second hard drive from my "old" PC, into the rig. On that old computer with Windows 7, the 4 TB HDD had been split into a ~2 TB E: partition and a ~2 TB F: partition -- both have important information on them. When I turned on my computer to make sure everything was fine, only the 2 TB E: partition was present in "This PC". Looking at the HDD in disk management, it shows the other ~2 TB as unallocated; only "properties" and "help" are clickable when right-clicking the unallocated space.


Both BIOS and disk management are showing that the HDD is 4 TB, yet the other half of the drive is gone. What can I do to get the partition and all its information to appear, or is it just lost forever? As I said, the F: partition has a lot of important to me files on it that'd be a pain to get back, so any help is appreciated.


Thanks.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

partition on HDD is showing unallocated

Hi Kyle_062,

My name is Lee an Independent Advisor.

To use the unallocated partition as a separte partition, all you need to do is to assign a drive letter in disk management (check this step:

If you want to merge it to the existing partition to have just a single Drive letter, here is a step by step procedure with screenshot on how to do it:

There is a down side of merging the two hard drive into one dynamic volume because we all know SSD last longer than HDD, if you only have 1 dynamic volume and in the event that the HDD failed, you won't be able to boot even if the SSD has no problem. Why not
keep two separtate drive volume, keep the OS in the SSD (for fault tolerance) and just use the regular Hard Drive as a separtate drive volume?

If my suggestion above did not help you, please reply back to let me know and I will assure you I will respond back as quickly as I can. Thank you and have a nice day!
