Western Digital Elements 2TB Hard Disk not recognized

Hi folks,

I have bought a WD Elements 2TB external drive with a usb 3.x cord.

When I connect it, I get on dmesg:

[25590.768307] usb 2-1.4: new high-speed USB device number 5 using ehci-pci

So it clearly is recognized by the USB port.

I reformatted it on another PC (Win10) to NTFS (which it was before anyway) and it doesn't show up in GParted or in my GNOME 3 environment.

Any ideas?
Thanks,

Pix

Have you used ntfs usb drives with this Arch install before? Do you have the ntfs-3g package installed?

What is the output of the "lsusb" command?

Or rather, `lsusb -t` or `lsusb.py -ui`. Either uas or usb-storage should take care of it.

Show also output of:

lsblk
lsscsi
fdisk -l

It should say more on the output of dmesg after you plug the disk, at least it should detect the disk capacity and how many partitions the disk has, even if you don't have installed everything that is needed to access those partitions.

Thanks a lot for your help.

I found out, that some WD portable drives seem to have a problem turning off their motor.

My old hard drive (same model) was having problems in a similar fashion, but was recognized. In dmesg, this was shown:

[41660.346091] sd 11:0:0:0: [sdb] Spinning up disk...

(and was taking WAY too long!)
Plus, this message wasn't showing up previously. Same kernal-version. Anyway,  must have been some bug in or something I did wrong and a reboot was part of the solution, perhaps?

I googled a bit and saw, that by sdparm --command=stop /dev/sXXX I would be able to stop the motor and re-connect the drive.

Well, it worked. The new drive was also working after sending the stop-command. But it's only a temporary solution.

The problem is at least known.
Just for some feedback.

Thanks for the all the help,
Pix

I have seen that some USB ports do not provided the needed power output to actually power an external HDD.  Are you certain that you used the same physical connection when it worked in the other os?
