Windows Server not seeing all of the TB disk

[2ilent8cho]

Got a server at home, which has 4x 6TB disks to create 2 RAID1 mirrors. These are SATA connected to the motherboard. I need to take a backup of the data so i bought another 6TB drive to make a copy of 1 of the mirrors, but i cannot make a 6TB partition on it as it only see's it as 1.5TB drive. This is connected via one of those USB HDD docks. It is converted to GPT so i dont get why i it cannot see it all, it can see all 6TB on the other drives.

 

Any ideas?

How is the drive connected?

USB dock. Like one of these, but not this actual one. https://www.ebuyer.com/709019-external-docking-station-for-2-5in-or-3-5in-sata-iii-6gbps-hard-drives-sdocku33ef

Tried using diskpart to delete the partitions, clean, then try again from scratch?

How old is the dock? It might be a size limitation on the USB to SATA chipset that you're using.

I was going to suggest that, misread the original post where he said 'like this one', I thought it was that one, which supports 6TB! haha

 

Yeah, as Norphy said, it'll most likely be the dock, I've had the same issue in the past.
