Should give someone a clue, something in the usb code that 10.2 didn't get
perhaps...
Thanks,
Jack

No, and no. It's a good idea, though. I can try it this weekend, if I
can run each OS via a USB memstick.
Just to follow up on myself, I tried this external USB drive on a
20150804-r286285 snapshot of FreeBSD/amd64 11-CURRENT on the same system,
as well as under Ubuntu 15.04.
The 4 TB Western Digital My Book 1230 works under both those operating
systems.
The drive is detected and works reliably when plugged in to a USB 2 port
on either 11-CURRENT or Ubuntu 15.04. It also works reliably when plugged
in to a USB 3 port on either OS, however, it isn't always detected reliably
under FreeBSD 11-CURRENT when unplugged and plugged in again (2 times out
of 3 attempts), but was detected every time without fail under Ubuntu 15.04.
So, it appears the hardware is okay; it seems the problem may lie with
FreeBSD 10.2.
Cheers,
Paul.
With this being such a commonplace drive, I'd hoped someone might pipe
up and say something along the lines of, oh, you have to add USB quirk XYZ
to get that model working under FreeBSD. No such luck, it seems.
Cheers,
Paul.

motherboard.
The drive probes unreliably when plugged in to a USB 3 port. It
reliably probes when plugged into a USB 2 port. However, it works in
neither cases. Attempting to dd from the drive results in a dd: /dev/da0:
Invalid argument.
FYI: I had been experiencing the same with a 2 TB WD MyBook on OS X
(Mavericks). The drive was being used for Time Machine backups, but it
would at irregular intervals it would just 'disconnect' itself. My
guess is that there's a firmware problem in the USB3 chip in those
drives.
After trying to get the issue fixed for almost half a year I returned
it and replaced it by a Seagate, which has been working flawlessly
ever since.
I'm just saying, perhaps the problem isn't with FreeBSD but with the
drive.
I'd love just to get to the randomly disconnects stage under FreeBSD
at this point. :-)
Up to now, I have been unable to read ANY data off the drive under
FreeBSD, either via USB 2 or USB 3. :-(
However, you have given me something to think about: does anyone know
of a 4 TB USB 2 or 3 drive that will work reliably under FreeBSD 10-STABLE
right now?
Cheers,
Paul.
