Hard drive size mismatch

[Vordermark]

I installed a new Seagate Barracuda 6TB hard drive as a secondary internal drive on an ACER Aspire M3203.

My problem is that the program Disk Management only shows the drive as 596 GB. I have tried other programs such a Seagate Discwizard, and the command line diskpart and they see the same size (596 GB).

I updated drivers with device manager, but most were already up to date. The ones that were not had no impact on the problem.

Any assistance would be greatly appreciated.

how many partitions are on that drive? (you should see only one ‘box’ for that drive in Disk Management)
is it formatted as NTFS?

[Vordermark]

Right now it is a single 596 GB Unallocated chunk in size.

I previously formatted using the program disk management to NTFS with the same 596 GB size. I also partitioned the drive using the command line diskpart but also the same 596 GB size.

did you initialise it as GPT?

if not, start an elevate command prompt and go into diskpart.
[ul]
[li]list disk (get the disk # for your drive)[/li][li]select disk (insert your # here)[/li][li]clean[/li][li]exit[/li][/ul]
go back to Disk Management and Windows should pop up a box to initialise. use GPT this time.

You do not say what OS you are using so will assume its Windows 10

In the windows search box type control panel and open it
Click administrative tools
Then double click computer management
Click disk management

Can you then take a screenshot of the full width of the hard drives and post it?

Something like this is what we need

I originally had initialized with GPT but I used the clean command to initialize again to confirm.

I am using Windows 10. You can see in Disk Management below with Disk 0 being the problem disk.

What is the make and model that is written on the drive and maybe the serial number?

Where did this drive come from?

Have you tried it on a different system and or as an external drive?

Final suggestion and not what you probably want to do is take it back to the store and exchange it if all else fails.
