I try to install to a ~480GB SDD that is in a carrier connected to a USB port. When trying to write partition changes to disk, the installer stops and complains that the root partition is offset by some multiple of 512 bytes. I try without success to find a way to set the SSD's physical and logical volume both sizes to 4096 bytes. Maybe the carrier's connection circuitry affects the perceived volume size? Maybe the SDD has to be internal and directly connected to the laptop? Thanks for any help. might you use something like gparted to handle the partitioning and then do the install? or simply linux fdisk?
