Windows 10: Windows 10 64bit does not see 12TB hard disk

I have a Seagate 12TB ST12000VN0007 hard drive. When I plugged into my computer, it showed 2TB instead of 12TB. Any suggestion?

hard drives dissappearing windows 10 64bit

Hello,

Thank you for posting your concern in Microsoft Community and we regret for the inconvenience.

I suggest you to consider the following points and check if it helps.

• If you are connecting the External hard drive via USB, try to check if similar issues occur when you use a different USB port. Also, connect the same hard drive to a different computer to ascertain the issue.
• Try to check for Hard disk defects using Disk Check utility in Windows.
• Update the drivers using Windows update settings(Update drivers in Windows 10) as well as check
  if the latest ones are available in the manufacturer's website.

Write to us with the updated status for us to be able to assist you further.

Thank You.

 

Hard disk partition not showing up.

Hi Muhammad,



Thank you for writing to Microsoft Community Forums.



This can happen if the Hard-disk drivers are not up-to date. I would suggest you to update the hard disk drivers first. To update the drivers, please follow the steps mentioned below:

1. Open Device manager.
   
2. Then Expand “Disk drives”.
   
3. Then Right click on the Hard-disk listed under this category.
   
4. Then click on Update drivers.
   
5. Alternatively you can also try to update the drivers from manufacturer’s website.
   

Once the hard-disk drivers are updated, you will need to allocate the last partition (it is not allocated according to the screenshot) and you will be able to view the partition.



Also note that sometimes the hard disk partitions/drives might be hidden in This PC or My Computer window due to a Registry key. If a DWORD with the name NoViewOnDrive or NoDrives is present under following key in Registry Editor:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer

Delete the DWORD and your drives will become visible in My Computer window.



Hope this helps.

 

External Hard disk contents are not visible.

Hi Pranoti,

For us to narrow down your concern with your external hard disk, we would like to know the following:

• Were there any changes made on your computer prior to the issue (e.g., updates, software installation)?
• To make sure that we have not missed on anything, what troubleshooting steps have you done so far?
• Do you hear any clicking sound when connecting your hard disk?

In the meantime, we suggest that you update all your device driver.

We look forward to your response.
