You do not show the dmesg so it's impossible to tell what the kernel thinks the drive is claiming. If the drive claims to be using 512-byte sectors, everything should work but potentially be slow due to the drive compensating for i/o into the middle of 4K sectors. If the drive is claiming to be using 4K sectors then the partitions should all have been automatically adjusted to start on 4K boundaries. .... Ken
