Hello,
I'm just trying to use an external USB dongle on a SATA 1TB Seagate Barracuda drive to pull the userdata off it before I wipe it and reload windows 10.
When I connect it via the USB dongle (to any of the) USB ports on my Windows 10 x64 machine, Disk Management detects the drive as a 16Terabyte (GPT Protective Partition drive).
I then connected the same drive to another windows 10 PC, and this time I could examine the drive under windows explorer. I don't want to use that PC because it is a work PC. I want to understand what setting or fix needs to be applied to get the drive to read on my home PC. I should note that the work PC did detect the drive as a 1TB GPT (Protective Partition) Drive, and it worked just fine.
I have the latest updates for windows 10 Pro (x64).
I also launched disk management under the Windows 10 local administrator account, disabled my AV, etc, the drive is still being detected as a 16 Terabyte GPT drive.
(Screenshot below) Right clicking on the Disk 3 location gives the option to convert the drive to a Dynamic Disk, but when I attempted that I received this error from Virtual disk manager "The operation is not supported by the object"
When right clicking, all the other options are grayed out.

The PC is new, has the updated BIOS, and the battery is just fine. The PC is a custom build within a year, by myself.
Here is what resolved the issue:
I pulled 'my' hard drive out of the system, including disconnecting any other drives I had connected to the system, and just inserted my client's drive into the system and amazingly it booted just fine. I was able to insert a USB stick into one of the USB ports and pull the data off.
But that still makes no sense. Why would it boot up but not be detected in windows explorer when simply added as an external drive?
Anyway, I think I'm all set.

Hi,
If the drive is 1TB you can format the drive and change a GUID Partition to MBR the size limit is 2TB.
"I then connected the same drive to another windows 10 PC, and this time I could examine the drive under windows explorer. "
If the drive is formatting in GPT only works with MB with GPT compatible.

Why would you ask me to format the drive when I clearly stated that I wanted to perform a data recovery?
Formatting the drive is going to prevent me from successfully recovering the data.

Sorry i assumed that I couldn't access the disc in all computers and the same is detectedwith the volume of 16 TB and not 1 TB.
One of the things I do is converter with DISKPART but if misused will lose the data and so I will not explain.
One of the things I would do was view BIOS updates because the disk controller.
One of the problems I see is "I should note that the PC did not detect the drive as a 1 TB (GPT Protective Partition) Drive, and it worked just fine." Not all computers due to the disk controller can work similarly when a disc is set to a volume higher than the existing one. For example you can set a volume of 500 TB to a flashdrive 250 MB when is formated to GPT this technique is used in sales on ebay,

Hi,
Have you checked the disk size in BIOS? If it was incorrect either, I recommend you change CMOS battery and reset BIOS to check the results. Make sure to follow the manual book of your computer or ask for help from manufacturer's support to avoid any unexpected issue.
If it's right in BIOS, I consider that this issue could be caused by SATA connection driver or the corrupted file system in this disk.
Please update the SATA driver here and run check disk tool:
Open CMD as admin and type commands below to scan disk error:
chkdsk /f /r
Let me know the update once you have tested my suggestions here.

I had this same problem but with a 500GB SATA HDD. When connected to my SATA to USB adaptor it would show up as a 16384GB "GPT Protective Partition". After some research and testing I found that the problem was just caused by using that particular SATA to USB adaptor. When I placed the drive in an extremal enclosure and connected that to USB, the drive showed up as normal. I've been using SATA to USB adaptors forever and have never come across this particular issue (and I'm a Sr. level IT engineer in multiple declines). So for others that may be getting this problem, just try connecting the drive using other means - either alternate external USB adaptors or via an internal/external SATA port if available.
