Other USB drives aren't causing the reported problem, including other USB 3TB
drives.
Maybe the issue is the computer is USB 2.0 and this particular 4Kn drive is in

Wouldn't using 'bs=4096' make things simpler and more obvious?

They are now shipping? When you use 'parted -l' does it say Sector size is
4096B/4096B or does it say 512B/4096B ? What model?

Thank you for your replies.
Yes, it is definitely BIOS problems as it doesn't allow to boot from
external drive directly (via BIOS boot order settings). It doesn't
show this drive at boot menu even after soft reboot. So BIOS
doesn't provide access to GRUB like to any other drives or USB
flashes.
Hi Bob,
it is probably not GRUB bug according to Your description - it looks to
be BIOS problem.

Currently I have no idea about Your HW, but it looks like Your xHCI (USB
3.0 controller) is not "native" part of the PC handled by BIOS, i.e.
BIOS cannot boot from any device connected to USB 3.0 p
Hi,
Is this a 4k native drive? (4k physical AND logical sector size) or is it a
512e drive?
In any case, if your system's BIOS does not present it as a boot option, you
could try GRUB's USB support, but it is a bit flaky (and doesn't directly
support usb3, so depending on how your USB contr
Hi, guys
I got new SEAGATE Expansion USB 3.0 and want to boot linux from it.
I have successfully booted various linuxes before with different
loaders from USB thumb flashes. But I cannot do it with this external
drive.
There are three problems: USB3, 4K sectors and >2TB.
I try grub2 (fedora 17)
