    5TB drive only showing as 561.53GB


    Hi

    Toshhiba 5TB X300 hard disk is only showing as 561GB is disk management.

    Have tried wiping partition & reformatting - still 561GB.

    Have used EaseUS Partition Master and did a quick scan for deleted partitions - still single 561GB partition

    and Paragon Partition Manager 14 and did a quick scan for deleted partitions - still single 561GB partition

    both show disk as 561GB

    Have tried converting disk to GPT - still 561GB.

    Tried Diskpart from elevated command prompt to delete the partitions and then create a primary partition - still 561GB

    Currently trying AOMEI Partition Manager on a "Full" scan.

    What has happened - what can I do to fix this?

    Cheers,

    @ArthurDent -

    What Motherboard do you have? Is it Intel based?

    If so, download and run this -

    Download Intel(R) Driver & Support Assistant

    Something about the Intel Chipset...

    Accept all updates (if any) and try partitioning as GPT again.

    Did you partition the entire drive as GPT?
    Try to partition it in GPT then post a screen shot of "disk management."

    What would you like to do with the drive?
    i.e. Install W10 on it or leave as just data?

    I've seen this before some time ago.

    Please post a Disk Manager whole image as an attachment. Expand the columns so we can read them.

    @ArthurDent -

    How many drives (HDD and SSD) do you have in your system?
    Which is the current boot drive?

    Thanks.

    Okay ...

    First, thanks for all of the replies.

    Second, some answers.

    The 5TB drive *was* the system drive in a 5 y.o. desktop (with Win 7 HP SP2) on it and, being the only drive in the system, also the data drive.

    I have bought a 240GB SSD and have done a clean install of Windows 10 Pro (Version 2004). The SSD is the boot drive. The 5TB drive was to be re-formatted as a data drive, together with a separate 1TB ex-laptop hard disk to keep a backup of important files (documents/pictures/videos) using @Try3's script (which I am currently running on both my laptop and my wife's laptop - regularly backing up files automatically to a 256GB SD Card).

    Currently (17:25 BST here in the UK ), AOMEI is 75% of its way through 'discovery'.

    When it has finished, I'll post a screen shot (expanded columns) of Disk Management for you to peruse.

    @Compumind Yes, the Mobo is Intel-based - a Gigabyte GA-H61M-DS2 DVI. Processor is i5-3340 Quad Core @ 3.1GHz. 8GB Ram.

    Will try your solution after AOMEI has finished its scan. I have downloaded the Intel® Driver & Support Assistant ready to go.

    Have you considered another OS?


    Here are a couple of ideas.

    There are several copies of Linux that you can live boot from a disk or USB drive as long as you can change your boot device or if the system tries to boot from other media first before going to the main drive. I suggest this because if it's an actual windows only issue, then you should see everything in a linux system. However, if there is some odd hardware issue with the drive, then you will see the same results in Linux.

    If you are using windows disk manager to re-partition the drive, you may not be seeing everything. This would be true if another part of the drive is a different file system that windows doesn't understand or if that part of the drive is corrupted. Windows may only be allowing you to access that small part of the drive because that's all it's seeing. If you look in windows disk manager and you don't actually see any other partitions in there, then you can see right there that windows isn't seeing the entire drive and so it's only going to let you play with what you see. This would be why re-partitioning and formatting hasn't gotten you anywhere.

    You may want to try a third party program. I think Esus Partition Magic may be free. I have had a couple of hard-drives in the past that windows didn't see everything and only by using a non-windows solution was I able to recover the drive.

    Hope that helps.

    Well a quick update.

    AOMEI finished its deep scan (or whatever it is called) and found no other partitions.

    I tried to run Intel Driver & Support Assistant - it tries to open Firefox (is the interface web-based?) and Firefox crashes. I try "Let windows find a solution" and that seemingly does nothing.

    Back to having a 561GB drive.

    I have a Linux Live on a USB stick. Next thing is to try Drew's solution and see what Linux can see.

    Worth a try. I keep a copy of gparted boot media for such situations.
