Hey there, daalb0209.

I'm not really familiar with the tool you posted a screenshot from, so would you please post a screenshot from Disk Management as well?
Make sure that you've initialized the drive properly by using GPT instead of MBR as MBR limits its drive capacity. Although it's a bit strange that you'd see 1277GB, as MBR limits the capacity to 2.2TB.

I'll be sure to check the screenshot once you've posted it.

Hi Boogieman_WD:
thanks for the reply
my system is is Chinese ..but you can still see GPT and the size of the disk

I did use initialize the drive by using GPT
is this a software problem or could it be the problem with the HDD itself?

 

[Boogieman_WD]

Yup, it does look like it's using GPT, so the only thing left is to try the basics like: trying the drive with a different port and cables (or even better with a different computer if possible) and testing the drive for errors with its manufacturer's diagnostic tool.

About Disk Management, here's how to access it (as this is probably a screenshot of the properties of the drive?): How to access Disk Management in Windows to manage hard drives. I wanted to see if there's any unallocated space left which you could partition and thus use the whole capacity of the drive.

@Boogieman_WD, this is a screen shot from Acronis True Image. OP try to use some other software to delete adn reinitialze your hdd, something like partition tools free ot minipartition tools, check on google best free partition manager and pick one. As Boogieman_WD said be sure to ckeck gpt format.

It's not the hdd. GO to the bios and change sata from raid to AHCI. Also, what os are you on?

this will delete everything on the disk. if drive is bootable, or is bootable you can boot from a bootable disk/usb and once at the windows installer hit ctrl + F10, it will bring up a cmd prompt.


in windows, you need to open a cmd window

type diskpart and hit enter

type list disk and hit enter, find your drives name

type select disk # and hit enter, # = your drives number

type convert gpt and hit enter, should say success.

format with windows or a tool that supports gpt. (also might need to enable uefi in bios (only if it doesn't work.).

saw that your using true image. If your installing from a backup you need to tell the program to use all of the disk space. or resize it after coping it over.

Don't think there is any unused space in the drive. and the first thing I did is change sata port and cable 🙁


@Dragos Manea I have reinitialze with seagate disk tool and MS disk manager. Still showing the same capacity

Sometimes aftermarket software can see much better free space or something hidden, give it a shot to this http://download.cnet.com/MiniTool-Partition-Wizard-Free-Edition/3000-2094_4-10962200.html, see if there anything hidden. If you can't do this with the software i linked to you then rma teh hdd, is faulty.

I had this exact same problem and the above is not the answer. I was able to resolve it though. The issue is with the motherboard Asus Z87-WS in my case. I have 4 drives on the SATA channel with RAID( two are 256 SSD RAID 0 and one is a non-RAID 2TB and the other a non-RAID 4TB) (which are recognized as the correct size) My mother board also has another group of 6 SATA channels which are not configured into a RAID. By moving the 8TB drive from the RAID channels to the other channels that do not have an option for RAID the 8TB drive was recognized correctly and I was able to format it to the full 7.4TB
