Re: USB3 3TB HDD boot

[Seth Goldberg]

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 controller is wired, you may not 
even be able to do that.)
