[GTALUG] 10TB drive seen as a 2TB drive (twice?)

[Evan Leibovitch]

It's not an Xmas present as it was bought a few weeks ago, but I'm trying
to install a 10TB WD (Red Pro) disk and it's not exactly going to plan.

My original plan was to put the disk into an external case, plug it in to
format and copy over files, then install it in the case.

The system already has an SSD as /dec/sda, and two disks one of 3TB and the
other of 4TB, all working fine.

When I attach the external drive, lsblock and fdisk -l both report TWO new
drives, /dev/sdd and /dev/sde, both of 2TB size. I went into set the disk
from DOS to GPT but the size didn't change;

Now fdisk -l reports:

Disk /dev/sdd: 2 TiB, 2199023255040 bytes, 4294967295 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: 49FDD63D-6C95-46F0-B7B1-650038D8FB9B

Disk /dev/sde: 2 TiB, 2199023255040 bytes, 4294967295 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

And cat /proc/scsi/scsi reports:

Host: scsi10 Channel: 00 Id: 00 Lun: 00
  Vendor: WDC WD10 Model: 1KFBX-68R56N0    Rev: 0200
  Type:   Direct-Access                    ANSI  SCSI revision: 04
Host: scsi10 Channel: 00 Id: 00 Lun: 01
  Vendor: WDC WD10 Model: 1KFBX-68R56NLUN1 Rev: 0200
  Type:   Direct-Access                    ANSI  SCSI revision: 04


The disk model is WD101KFBX and its specs can be found here.

All of the online guides I've consulted say that the full capacity of the
drive should be visible once I switch it to GPT mode.

Is this a USB limitation? Or is there something else I need to change? I've
attached the output of hwinfo if that's any help.

Thanks for any suggestions!
